VERIFIED GRADED A+
True or false: metabolism is a controlled set of biochemical reactions that occur
in living organisms in order to maintain life. - CORRECT ANSWER -True
True or fase: enzymes slow down chemical reactions to conserve energy -
CORRECT ANSWER -False. They speed up (catalyze) chemical reactions
Term for metal ions that assist enzymes during catalysis reaction - CORRECT
ANSWER -Cofactors
What is catabolism? - CORRECT ANSWER -The process of breaking
down larger molecules into smaller ones (and useful energy sources)
Upon cellular injury, which metabolic process is involved during the growth
and repair phases of the cell? - CORRECT ANSWER -Anabolism. It is the
metabolic process to build up small molecules into larger ones during growth
and repair.
An organism that obtains its energy (derives ATP) from photons of light is
called_______________. - CORRECT ANSWER -Phototrophic
microorganism
An organism that derives energy by removing electrons from elemental sulfur is
classified as _______________. - CORRECT ANSWER -Lithotroph
,Describe the energy transfer process relative to both ADP and ATP -
CORRECT ANSWER --ATP has the energy (phosphate group) to donate,
and ADP can accept energy in the form of a phosphate group through
photophosphorylation, substrate-level phosphorylation, or oxidative level
phosphorylation.
-ADP can be phosphorylated into ATP (ADP + Pi -----> ATP)
-ATP can be dephosphorylated into ADP(ATP-----> ADP + Pi)
This phosphorylation occurs in the mitochondria or chemotropic eukaryotes -
CORRECT ANSWER -Oxidative phosphorylation
The catabolism of a single molecule of glucose goes through what 3 distinct
transitions? - CORRECT ANSWER -1. Glycolysis
2. Fermentation or respiration
3. Electron transport chain (ETC)
True or false: in the absence of oxygen, fermentation products 2 ATP -
CORRECT ANSWER -False
What is the primary byproduct of the TCA cycle? - CORRECT ANSWER -
NADH and FADH2
True or false: the reactants of the TCA cycle directly enter and fuel the electron
support chain. - CORRECT ANSWER -False
What are the two main roles of glucose 6-phosphate in the cell? - CORRECT
ANSWER -1. Prevents glucose from diffusing out of the cell
, 2. Serves as signal molecule to the cell that glycolysis is about to begin
What is the most energetic transition in the catabolism or glucose? -
CORRECT ANSWER --The ETC yields 34 ATP
-Glycolysis and fermentation (or respiration) yield only two ATP
The reactants of the chemical equation are to the ______ of the arrow. -
CORRECT ANSWER -Left
In the absence of glucose, what cannot be used as an alternative energy source?
- CORRECT ANSWER -Nucleic acids
For the catabolism of proteins and lipids, which enzymes are used? -
CORRECT ANSWER -Lipases and proteases
True or false: the B-oxidation pathway is responsible for the anabolism of fatty
acid chains. - CORRECT ANSWER -False. The B oxidation pathway is
responsible for the catabolism of fatty acid chains
True or false: Plants, algae, and bacteria all have chloroplasts - CORRECT
ANSWER -False. Only plants and algae have chloroplasts.
How many turns or repetitions of the Calvin cycle are required to generate one
molecule of glucose? - CORRECT ANSWER -6
True or false: dark reactions can take place in the presence or absence of light -
CORRECT ANSWER -True. The term dark reactions (also known as
Calvin cycle) simply denotes the second stage of photosynthesis - does not
actually require darkness
