True or False. The β-oxidation pathway catabolizes the fatty
acid chains of lipids.
True
True or False. Metabolism is a controlled set of biochemical
reactions that occur in living organisms in order to maintain
life.
True
What is the term for metal ions that assist enzymes during the
catalysis reaction?
Cofactor
The catabolism of a single molecule of glucose goes through
what 3 distinct transitions?
1. Glycolysis
2. Fermentation or Respiration
3. Electron Transport Chain
What is the most energetic transition in the catabolism of
glucose?
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?
catabolism
Define catabolism
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
A
, True or False: The Calvin cycle must occur in the absence of
light.
false
Describe the energy transfer process relative to both ATP and
ADP.
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
Glucose, 2NAD+
True or False. The reactants of the TCA cycle directly enter and
fuel the electron transport system.
False
The process of carbon fixation begins with which of the
following reactants: select all that apply.
A. ATP
B. Glyceraldehyde-3-phosphate
C. CO2
D. NADPH
E. H2O
A, B, C, D, E
In phosphorylation, the light reactions always occur where?
The process of converting light energy into chemical energy
(photophosphorylation) always occurs in the membrane.
In the absence of glucose, which of the following can be used as
alternative energy sources? Select all that apply.
A. Lactose
B. Nucleic acids
C. Carbohydrates
D. Lipids
A, C, D
An organism that obtains its source of carbon from inorganic
molecules such as carbon dioxide is referred to as a
____________?
autotroph
