Answer:
Respiration uses NADH as an electron carrier, fermentation does not
Explanation:
Respiration is the process of chemical reactions, in oxidising food to generate energy.
Fermentation is chemical breakdown of organic substrate, like glucose, by microrganisms like bacteria & yeast.
Difference between them is that : Respiration process uses NADH in oxidative phosphoralytion for ATPs . However, fermentation doesn't include use of NADH in oxidative phosphoralytion for ATPs.

The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside?
osmosis
diffusion
passive transport
active transport
If the concentration of sodium on the inside of the cell is 20 mM, and the outside is 115 mM, then active transport will move sodium from the inside to the outside.
What is active transport?Active transport is a type of cellular transport mechanism that occurs against a concentration gradient.
In active transport, a molecule and/or ion is transported from a region of low concentration to a region of high concentration.
Active transport requires energy (usually in the form of ATP) to move substances against a gradient.

Please help i dont have much time last day of 9 weeks and will help me not fail
Answer:
Throughout history, along with the development in microscopic technology, scientists were able to form the cell theory that: a) All cells come from pre-existing cells. b) All living organisms are composed up of one or more cells. c) Cells are the basic structure, function, and organization of all living organisms. Additionally, scientists, such as Louis Pasteur in the late 19th century, disproved the theory of spontaneous generation. Now, if one does not believe in this theory, they could either use a microscope and observe cellular division or reproduction/growth of organisms, or review the research from Matthias Schleiden, Theodor Schwann, Rudolf Virchow, etc. With the modern developments in scientific technology, people can observe the cell theory at their fingertips.

What is an example of a feedback loop on someone with Parkinson's disease?
Explanation:
Genetics has taught us a great deal about disorders in which the underlying cause is complex and, thus, often relegated to the catch all “sporadic” diseases. However, the gap between identifying genes and understanding their pathogenic pathways remains enormous. In this context, the new study by Mazzulli et al. (2011) in the current issue of Cell uncovers a tractable biochemical relationship between two complex diseases, the neurodegenerative disorder Parkinson's disease and the lysosomal disorder Gaucher disease, in which lipids accumulate in central organs.
Parkinson's disease is characterized by two pathological features. First, neurons die in regions of the brain, which control the normal fluidity of movement. This leads to the clinical picture of tremor, stiffness, slowness, and difficulties with posture. Second, proteins and lipids accumulate into structures, called Lewy bodies, inside surviving neurons (Gai et al., 2000). The synaptic protein α-synuclein is one key component of Lewy bodies, and variations in its gene, SNCA, are associated with inherited and sporadic Parkinson's disease (Hardy, 2010). When present in Lewy bodies, α-synuclein is aggregated; however, it is unclear which species causes cell death, the aggregated form or some intermediate in the aggregation pathway, such as soluble oligomers.
Gaucher disease is an autosomal recessive disorder caused by mutations in the GBA gene, which encodes the enzyme glucocerebrosidase (GCase). Parents and grandparents of patients with Gaucher disease have unusually high rates of Parkinson's disease, suggesting that these mutations are risk factors for Parkinson's disease (Velayati et al., 2010). Although mutations underlying Gaucher disease are loss of function, patients with Parkinson's disease always carry one wild-type GBA allele and thus possess at least 50% of normal enzyme function. Furthermore, there is no obvious correlation between the type of GBA mutation (i.e., completely inactive or one with some residual enzyme activity) and the risk of Parkinson's disease (Velayati et al., 2010). Thus, the genetic mechanism by which GBA mutations promote Parkinson's disease is still not clear.
GCase catalyzes the conversion of glucocerebroside to glucose and ceramide inside the lysosome. One possible link between GCase function and Parkinson's disease risk is α-synuclein. The main degradation pathway of α-synuclein is via lysosomal processing, and GCase interacts with α-synuclein in acidic environments, such as the lumen of the lysosome (Yap et al., 2011). Interestingly, α-synuclein has been shown to inhibit vesicle transport between the endoplasmic reticulum (ER) and the Golgi apparatus, the main trafficking route for GCase to reach the lysosome. Thus, increased expression of α-synuclein should decrease levels of GCase in lysosomes. As an aside, mutant α-synuclein can inhibit chaperone-mediated autophagy, a process by which some substrates are imported into and degraded by the lysosome . Therefore, lysosomal dysfunction could increase α-synuclein levels, and α-synuclein could inhibit lysosomal function in multiple ways.
Indeed, the central idea in the paper by Mazzulli et al. is that this exact type of positive feedback loop occurs in Parkinson's disease patients carrying GBA mutations. To model the loss of enzyme function seen in these patients, the authors decrease the expression of GBA in mouse neurons to ∼50% of control conditions. Over a few days in culture, the neurons loose lysosomal turnover of long-lived proteins, including α-synuclein. The author observe this phenotype in primary neurons and in neurons reprogrammed from induced pluripotent stem cells (iPSCs), with the latter having both copies of GBA mutated, as found in neurons from patients with Gaucher disease.
The authors then characterize the formation of α-synuclein oligomers in cells, in mice, and in brains from people who had mutations in GBA. Soluble oligomers are found in neuronopathic forms of Gaucher disease, as well as Parkinson's disease patients heterozygous for GBA mutations. This observation suggests that the emergence of oligomers is not correlated with Lewy bodies but rather is a more fundamental consequence of GBA mutations. Mazzulli and colleagues also show that expression of α-synuclein impacts the trafficking of GCase from the ER-golgi to the lysosome, indicating that α-synuclein affects lysosomes irrespective of the presence of GBA mutations.
Simplistically, the data by Mazzulli and colleagues suggest the following model: a rise in α-synuclein levels through mutation, response to stress, or neuronal maturation (Li et al., 2004) inhibits the normal negative feedback loop of degradation by the lysosome, leading to more α-synuclein and more inhibition . Then the system would transition from one stable state to a second one that is self-sustaining, unless another pathway intervenes to stop it.

Flowers are a reproductive structure for some plants. The corpse flower blooms for a short period of time, and it smells like a mixture of rotten food, decaying organisms, and garbage. This repulsive scent attracts pollinating insects to the flower.
Do you think the corpse flower’s smell meets the definition of an adaptation as stated in the video? Explain your response.?
Answer:
Yes. Because the flower blooms for only a short time, it needs to attract pollinators quickly so that it can reproduce. If it didn’t have this adaptation, the plant might not be able to produce offspring.

I need help figuring out which graph to use.
This is for Earth Space Science, not biology.
Circle graphs/Pie Charts are best used to compare the parts of a whole.
You want to give a visual representation of percentages as a relative proportion of the total of a circle. They are a type of graph even though they do not have any axes. A pie chart is a circle divided into sectors (think of them as the slices of a cake).
Circle Graphs are used to compare the parts of a whole. Circle graphs represent data visually in the same proportion as the numerical data in a table: The area of each sector in a circle graph is in the same proportion to the whole circle as each item is to the total value in the table. Constructing an accurate circle graph is difficult to do without a computer. This is because you must first find each part of the whole through several elaborate calculations and then use a protractor to draw each angle. This leaves a lot of room for human error. Circle graphs are best used for displaying data when there are no more than five or six sectors, and when the values of each sector are different. Otherwise, they can be difficult to read and understand.
