Question:
True or False: as movement requires energy, metabolism can be defined as a
controlled set of biochemical reactions that occur in only motile organisms in order to maintain life.
Answer:
False
(It occurs in all living organisms.)
Question:
Define anabolism.
Answer:
Anabolism is the process of building up or biosynthesis of macromolecules from small molecular units into much larger complexes. 1 / 3
Question:
In order to convert proteins into amino acids, which metabolic process would be active?
Answer:
Catabolism
Question:
An organism that derives its energy from photons of light is called ____?
Answer:
Phototrophic microorganism
Question:
An organism that derives its energy by removing electrons from elemental sulfur would be classified as a ____?
Answer:
Lithotroph
Question:
A reactive intermediate would be present in which phosphorylation process?
Answer:
Substrate-level phosphorylation 2 / 3
Question:
What is one of the main functions of light reactions?
Answer:
Similar to the electron transport chain, one of the main functions of light reactions is to generate a proton concentration gradient to generate ATP.
Question:
True or False: Dark reactions can occur in the presence or absence of light.
Answer:
True.
The term 'dark reactions' (also known as the Calvin Cycle) simply denotes the second stage in photosynthesis—dark reactions do not actually require darkness in order to occur.
Question:
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes.
Answer:
