Question 3
What is a cofactor? And give a general example.
Your Answer:
A cofactor is a small chemical component that assist enzymes during
catalysis reaction. A general example of a cofactor is metal ions.
A cofactor is a small chemical component that assists an
enzyme during the catalysis reactions. A cofactor is usually
metal ions.

Question 4
Define anabolism.
Your Answer:
Anabolism is the process of building up smaller molecules units into
larger complexes.
Anabolism is the process of building up or biosynthesis of
macromolecules from small molecular units into much
larger complexes.

Question 5
In order to convert proteins into amino acids which metabolic process
would be active?
Your Answer:
In order to convert proteins into amino acids, catabolism would be
active because it will break the proteins into the amino acids.
Catabolism would be active as proteins are made up of
amino acids. Therefore the process described (proteins into
amino acids) is the breakdown, or catabolism of protein.

Question 6
Describe the energy transfer process relative to both ATP and ADP.
Your Answer:
The energy transfer process relative to both ATP and ADP is that ATP
has energy (phosphate) to donate, while ADP can accept energy
(phosphate group) to become ATP.
ATP has the energy (phosphate group) to donate while ADP
can accept energy in the form of a phosphate group. Thus,
ATP can be reduced (ATP ADP + Pi) while ADP can be
built into ATP (ADP + Pi ATP).

Question 7
From what source do chemotrophs acquire energy?
Your Answer:
Autotroph
Chemotrophs acquire energy from preformed chemicals
found in the environment.
pts
Question 8
An organism that derives its energy by removing electrons from
elemental sulfur would be classified as a __________?
Your Answer:
Litotroph
Lithotroph

Question 9
This phosphorylation process occurs in the mitochondria of chemotropic
eukaryotes.
