Describe how facilitated diffusion helps large molecules cross cell membranes. What kinds of proteins are involved?

Answers

Yeah yeah so :D,

Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.

So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)

the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.

Large or polar molecules like glucose can't pass through the phospholipid bilayer. Smaller molecules usually diffuse freely for example water and CO2.

Large molecules like glucose diffuse through channels. This is a form of passive transport.  Carrier proteins are involved.

In another population, the white spot allele frequency is 0.55. What percentage of the moth population has white spots?

Answers

Answer:

The correct answer is - 30.25%

Explanation:

Allele frequency in a population is the number of a particular allele in the population divided by the total number of all alleles present in the population for the particular gene.

The population has the allele frequency or q = 0 .55

So, the percentage of the white spots moth in this moth population would be -

q^2 = (0.55)^2

q^2 = 0.3025

q^2 = 0.0325 *100

= 30.25 %

From the provided choices, which color of light does the pigment chlorophyll absorb the most?

A) green
B) Orange
C) blue
D) yellow

Help!!! plz

Answers

Answer:

What color light is best absorbed by chlorophyll?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Explanation:

therefore it is blue

Answer:

Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.

Explanation:

So in conclusion the answer will be Blue <3 Hope this helps!

What is the function (purpose) of the valves which connect the heart chambers?

allows blood to flow between the two atria
allows blood to flow from the atria to the ventricle
prevents blood from flowing into the atria when ventricle pumps
allows blood to flow between the two ventricles

Answers

Answer:

allows blood to flow between the two atria

allows blood to flow from the atria to the ventricle

prevents blood from flowing into the atria when ventricle pumps

allows blood to flow between the two ventricles

prevents blood from flowing into the atria when ventricle pumps

The valves allow the blood to flow in only one direction so for example when the left ventricle contracts the mitral valve prevents the blood from going back into the left atrium.

In chemiosmosis in mitochondria, protons flow from the intermembrane space into the matrix. In what direction do protons flow during chemiosmosis in chloroplasts

Answers

Answer:

Protons flow from the thylakoid space into the stroma of the chloroplast

Explanation:

Chemiosmosis is one of the two events that occur in oxidative phosphorylation (the other being electron transport chain). Chemiosmosis, which occurs to synthesize ATP in both cellular respiration and photosynthesis, is the process whereby protons (H+) move across a membrane via osmosis. In other words, chemiosmosis builds the proton gradient required to power ATP synthesis via the aid of an enzyme called ATP synthase.

In cellular respiration, chemiosmosis occurs when protons flow from the intermembrane space into the matrix while in PHOTOSYNTHESIS, cheniosmosis occurs when protons flow from the thylakoid space into the stroma of the chloroplast.

The flow of protons takes place from the thylakoid space into the stroma of the chloroplast during the chemiosmosis in chloroplasts.

What is chemiosmosis?

It is one of the events, which takes place during oxidative phosphorylation. It generally takes place to produce ATP in both the process of photosynthesis and cellular respiration. In the process, the protons move across a membrane through osmosis.

It can also be stated that building of the proton gradient for the synthesis of ATP takes place by chemiosmosis with the help of an enzyme known as ATP synthase.

Chemiosmosis takes place when flow of protons takes place from the intermembrane space into the matrix during cellular respiration. While in photosynthesis, chemiosmosis takes place when flow of protons takes place to the stroma of the chloroplast from the thylakoid space.

Thus, in chloroplasts, chemiosmosis takes place when flow of protons takes place from the thylakoid space into the stroma.

Answer:

A. alternation of generations

Explanation:

Basically, a plant's life cycle has two main parts, namely a diploid and a haploid phase. Since the plant alternates between these two phases in its life cycle, the alternation is typically called the alternation of generations.

A. alternation of generations

Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.
