=Choose the pair of terms that correctly completes this sentence: Catabolism is to anabolism as exergonic is to ________.
endergonic
-Chapter 8-
Most cells cannot harness heat to perform work because
temperature is usually uniform throughout a cell.
-Chapter 8-
Which of the following metabolic processes can occur without a net influx of energy from some other process?
A) ADP + i → ATP + H2O
B) 6 CO2 + 6 H2O → C6H12O6 + 6 O2
C) C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
D) glucose + fructose → sucrose
E) amino acids → protein
B) 6 CO2 + 6 H2O → C6H12O6 + 6 O2
-Chapter 8-
If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to
add more of the enzyme
-Chapter 8-
Some bacteria are metabolically active in hot springs because
their enzymes have high optimal temperatures.
-Chapter 8-
If an enzyme is added to a solution where its substrate and product are in equilibrium, what will occur?
Nothing; the reaction will stay at equilibrium.
-Chapter 9-
The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the
H+ concentration across the membrane holding ATP synthase.
-Chapter 9-
Which metabolic pathway is common to both fermentation and cellular respiration of a glucose molecule?
glycolysis
-Chapter 9-
In mitochondria, exergonic redox reactions
provide the energy that establishes the proton gradient.
-Chapter 9-
The final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation is
oxygen
-Chapter 9-
What is the oxidizing agent in the following reaction?
Pyruvate + NADH + H+ → Lactate + NAD+
pyruvate
-Chapter 9-
When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs?
The pH of the matrix increases.
-Chapter 9-
Most CO2 from catabolism is released during
the citric acid cycle
-Chapter 10-
The light reactions of photosynthesis supply the Calvin cycle with
ATP and NADPH
-Chaper 10-
Which of the following sequences correctly represents the flow of electrons during photosynthesis?
H2O → NADPH → Calvin cycle
-Chapter 10-
How is photosynthesis similar in C4 plants and CAM plants?
In both cases, rubisco is not used to fix carbon initially.
-Chapter 10-
________ can nourish themselves beginning with CO2 and other nutrients that are inorganic.
Autotrophs, but not heterotrophs
-Chapter 10-
Which of the following does not occur during the Calvin cycle?
release of oxygen
-Chapter 10-
In mechanism, photophosphorylation is most similar to
oxidative phosphorylation in cellular respiration
-Chapter 10-
Which process is most directly driven by light energy?
removal of electrons from chlorophyll molecules
