Question 1
2 / 2 pts
True or False: As movement requires energy, metabolism can be defined as a
controlled set of biochemical reactions that occur in
... [Show More] only motile organisms in order to
maintain life.
False
Metabolism occurs in all living organisms, not just those that move.
Question 2
2 / 2 pts
True or False: Enzymes slow down chemical reactions to conserve energy.Correct!
False
Enzyme catalyze (speed up) chemical reactions.
Question 3
5 / 5 pts
What is the term for metal ions that assist enzymes during the catalysis reaction?
Your Answer:
cofactors
Cofactors are usually metal ions and assist enzymes during the catalysis
reaction.
Question 4
5 / 5 pts
Define anabolism.
Your Answer:
Building up smaller chemical building blocks.
Anabolism is the process of building up or biosynthesis of
macromolecules from small molecular units into much larger complexes.
Question 5
0 / 5 pts
In order to convert proteins into amino acids which metabolic process would be active?
Your Answer:
glycolysis
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
10 / 10 pts
Describe the energy transfer process relative to both ATP and ADP.
Your Answer:
ATP has the energy to donate to ADP while ADP is able to recieve energy from ATP.
Therefore ATP-Pi--> ADP, ADP+Pi--> 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
dephosphorylated (ATP
⟶
ADP + Pi), while ADP can be phosphorylated into ATP (ADP + Pi
⟶
ATP).
Question 7
2 / 2 pts
An organism that derives its energy (generates ATP) from photons of light is called a
_________?
Your Answer:
Phototrophs
Phototrophic microorganism
Question 8
0 / 2 pts
An organism that obtains its source of carbon from inorganic molecules such as carbon
dioxide is referred to as a ____________?
Your Answer:
chemotrophs
Autotroph
Question 9
2 / 2 pts
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes.
Photophosphorylation
Correct!
Oxidative phosphorylation
Substrate-level phosphorylation
Question 10
5 / 5 pts
The catabolism of a single molecule of glucose goes through what 3 distinct transitions?
Your Answer:
1) glycolysis
2) fermintation or respiration
3) ETC
The breakdown of glucose goes through (1) Glycolysis then (2)
Fermentation or Respiration and finally through (3) the electron transport
chain (ETC).
Question 11
5 / 5 pts
