Q1 QUESTION 1 OF 43
Page 1
, True or False: The ΔG value for a particular reaction is -78kJ/mol. This value indicates the reaction is spontaneous.
CORRECT ANSWER
true
RATIONALE
A negative ΔG value signifies that the Gibbs free energy of the products is lower than that of the reactants, indicating that the reaction can proceed
spontaneously without the input of external energy. Spontaneity is determined by ΔG; thus, -78 kJ/mol confirms the reaction's favorable thermodynamic
conditions.
Q2 QUESTION 2 OF 43
True or False: A biochemical metabolic pathway is a single reaction that converts starting material into products.
CORRECT ANSWER
false
RATIONALE
Biochemical metabolic pathways consist of a series of interconnected enzymatic reactions that transform substrates through multiple steps, rather than a
singular reaction. This complexity allows for regulation and integration of metabolic processes, highlighting the pathway's role in cellular metabolism.
Q3 QUESTION 3 OF 43
True or False: A biochemical metabolic pathway is a series reaction that converts starting material into products.
CORRECT ANSWER
true
RATIONALE
Biochemical metabolic pathways consist of a sequence of enzymatically catalyzed reactions that transform substrates into specific products, illustrating
the coordinated regulation of metabolic processes. This principle underpins the conversion of raw materials into energy or cellular components essential
for life.
Q4 QUESTION 4 OF 43
True or False: The citric acid cycle occurs in the presence of oxygen.
CORRECT ANSWER
true
RATIONALE
The citric acid cycle, also known as the Krebs cycle, operates within the mitochondria, where it contributes to aerobic respiration by oxidizing acetyl-CoA
to produce ATP, NADH, and FADH2 in the presence of oxygen. While it does not directly consume oxygen, it relies on an aerobic environment to facilitate
the electron transport chain, which regenerates NAD+ and FAD for continued cycles.
