Questions and Correct Detailed Answers |
New Update 2025
True or False. The β-oxidation pathway catabolizes the fatty acid chains of lipids. -
ANSWERS True
True or False. Metabolism is a controlled set of biochemical reactions that occur in
living organisms in order to maintain life. - ANSWERS True
What is the term for metal ions that assist enzymes during the catalysis reaction? -
ANSWERS Cofactor
The catabolism of a single molecule of glucose goes through what 3 distinct
transitions? - ANSWERS 1. Glycolysis
2. Fermentation or Respiration
3. Electron Transport Chain
What is the most energetic transition in the catabolism of glucose? - ANSWERS
Throughout the electron transport chain up to 34 molecules of ATP are formed.
Glycolysis and fermentation/respiration each yield only 2 STP.
In order to convert proteins into amino acids which metabolic process would be
active? - ANSWERS catabolism
, Define catabolism - ANSWERS breakdown of larger molecules into subunits
How many ATP does the tricarboxylic acid (TCA) cycle produce per pyruvate?
A. 1 ATP
B. 2 ATP
C. 4 ATP
D. 34 ATP - ANSWERS A
True or False: The Calvin cycle must occur in the absence of light. - ANSWERS
false
Describe the energy transfer process relative to both ATP and ADP. - ANSWERS
ADP undergoes phosphorylation to become energy-rich ATP. A phosphoryl group is
added to ADP by way of photophosphorylation, substrate-level phosphorylation,
or oxidative-level phosphorylation. ATP is hydrolyzed in order to become ADP.
Identify the reactants of the following chemical equation:
Glucose + 2NAD+ → 2 NADH + 2 Pyruvate + 2 ATP - ANSWERS Glucose, 2NAD+
True or False. The reactants of the TCA cycle directly enter and fuel the electron
transport system. - ANSWERS False
The process of carbon fixation begins with which of the following reactants: select
all that apply.
A. ATP
B. Glyceraldehyde-3-phosphate
