Answer: B and D

Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.

Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.

This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.

Hope this helped.

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?
Romashka [77]

Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:

1. Absorbed CO2 is added to RuBP and 6C sugar is formed.

2. Breaking of 6C sugar into two  3-phosphoglycerate molecules

3. ATP gives phosphate group  to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.

4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH

5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called  fructose-1,6-biphosphate which is further converted to fructose-6-phosphate

6. Enzyme  isomerase converts fructose-6-phosphate to glucose-1-phosphate

How is an insulin gene removed from a strand of human DNA?
Vlada [557]
The human gene for insulin production is identified and removed using enzymes called restriction enzymes. The same restriction enzymes are used to cut open a plasmid (a small, circular section of DNA).
