what is the proton gradient in cellular respiration?

Answers

Answer 1

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Answer 2

A proton gradient is a difference in the concentration of protons (H+) across a membrane. In cellular respiration, a proton gradient is created by the electron transport chain (ETC) in the mitochondria.

The ETC is a series of proteins that shuttle electrons from NADH and FADH2 to oxygen. As the electrons are shuttled, they lose energy, which is used to pump protons out of the mitochondrial matrix into the intermembrane space.

This creates a concentration gradient, with more protons in the intermembrane space than in the mitochondrial matrix.

The proton gradient is used to power ATP synthesis. The enzyme ATP synthase, which is located in the inner mitochondrial membrane, uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate (Pi).

The proton gradient is a key part of cellular respiration, and it is essential for the production of ATP. Without the proton gradient, ATP synthesis would not be possible, and cells would not be able to produce the energy they need to function.

what is the dominant impact that humans have on alpine glaciers?

Answers

The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.

Answer:

Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

what molecule makes instructions for proteins and is located inside a eukaryotic nucleus

Answers

Answer:

DNA stores that info

Explanation:

In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).

The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.

The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.

The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.

During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.

The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

Three types of macromolecules are mentioned in the video that are digested and ABSORBED in the small intestine. What do they all get absorbed into first?

Lacteals

Epithelial cells

Capillaries​

Answers

Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".

The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.

Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.
