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 ly require darkness in order to occur.

Question:

This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes.

Answer:

Oxidative phosphorylation
