Answer:

Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.

Which of the following is a true statement?Anabolic pathways build molecules, require energy, and are endergonic.Anabolic pathwa

expeople1 [14]

Answer:

A: Anabolic pathways build molecules, require energy and are endergonic

Explanation:

Anabolism and catabolism are the two important process of metabolism - a process through which cells get energy to drive various processes within the body and get rid of toxic wastes.

Anabolic and catabolic reactions can be described as opposing sides of the same coin. While anabolism refers to the various reactions that build up molecules within the cell, catabolism has to do with the breakdown of big or complex molecules into smaller ones.

Both processes involves energy. Anabolic reactions require energy to drive the building up process and therefore referred to as endergonic reactions. On the other hand, catabolic reactions liberate energy during the breaking down of complex molecules and therefore referred to exergonic reactions.

A good example of anabolic reaction is photosynthesis which involves the building up of carbohydrate (glucose) using carbon-dioxide, water molecule and energy while a good example of catabolic reaction is respiration which involves the breakdown of carbohydrates into carbon-dioxide, water molecules and the release of energy.

Hence, the only correct option is A.

Are the cell membrane and mitochondrial membrane permeable to gases

Fofino [41]

Answer:

They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.

Ocean acidification impacts are: 1. 2. 3. 4.

____ [38]

Explanation:

In the 200-plus years since the industrial revolution began,concentration of carbon dioxide in the atmosphere has increased due to human actions.During this time,the pH of surface ocean waters has fallen by 0.1 pH units.This might not sound like much,but the pH scale is logarithmic,so this change represents approximately a 30 percent increase in acidility.
