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.
False
Metabolism occurs in all living organisms, not just those that move.
Question 2
pts
True or False: Enzymes slow down chemical reactions to conserve energy.Correct!
False
Enzyme catalyze (speed up) chemical reactions.
Question 3
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
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
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
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
pts
An organism that derives its energy (generates ATP) from photons of light is called a
_________?
Your Answer:
Phototrophs
Phototrophic microorganism
Question 8
pts
An organism that obtains its source of carbon from inorganic molecules such as carbon
dioxide is referred to as a ____________?
