B only

Answer 1

Q. Which type of organism would be most likely to use inorganic electron donors to generate ATP? (Check all that apply!)

Answer : chemolithotroph. They are organism that used inorganic electron donor to generate ATP.

Phototrophs and autotrops can use both inorganic and orhmganic electeon donor.

Heterothophs and chemoorganotrophs use organic electron donor

Q. Enzymes are made from long, folded polymers. What is the polymer?

Answer : Polypeptide. Enzymes are made up of protein and protein is a polymer of peptides.

Q. Consider the biochemical pathway: A → B → C

Enzyme 1 catalyzes A → B

Enzyme 2 catalyzes B → C

If enzyme 2 is inactive, which of the following compounds will accumulate?

Answer : B only. Since enzyme 1 is still active it still will continue to form B from A. But as the enzyme 2 is inactive B could not be converted to C. So, B will accumulate.
