Question 1

Which eukaryotic organelle is primarily responsible for synthesizing transmembrane proteins, secretory proteins, and N-linked oligosaccharide core additions?

Rough endoplasmic reticulum Smooth endoplasmic reticulum Peroxisome Lysosome

Correct Answer:

Rough endoplasmic reticulum

Question 2

During transcription in eukaryotic cells, in which direction does RNA polymerase synthesize the pre-mRNA transcript, and what is the orientation of the template DNA strand it reads?

Synthesizes 5' to 3'; reads template 3' to 5' Synthesizes 3' to 5'; reads template 5' to 3' Synthesizes 5' to 3'; reads template 5' to 3' Synthesizes 3' to 5'; reads template 3' to 5'

Correct Answer:

Synthesizes 5' to 3'; reads template 3' to 5'

Question 3

How does a reversible competitive inhibitor alter the kinetic parameters Michaelis constant (Km) and maximum velocity (Vmax) of an enzymatic reaction?

Increases apparent Km while leaving Vmax unchanged Decreases apparent Km while leaving Vmax unchanged Decreases Vmax while leaving Km unchanged Decreases both apparent Km and Vmax by the same ratio

Correct Answer:

Increases apparent Km while leaving Vmax unchanged

Question 4

In the complete breakdown of one molecule of glucose via aerobic glycolysis, what is the net yield of ATP synthesized strictly by substrate-level phosphorylation prior to pyruvate entering the mitochondria?

2 ATP 4 ATP 6 ATP 32 ATP

Correct Answer:

2 ATP

Question 5

How does an uncoupling agent such as 2,4-dinitrophenol (DNP) alter mitochondrial electron transport and ATP synthesis?

It dissipates the inner membrane proton electrochemical gradient, stimulating electron transport while halting ATP synthesis It binds to Complex IV (cytochrome c oxidase), blocking electron transfer to oxygen and stopping the proton pump It inhibits the F1 catalytic subunit of ATP synthase without altering the proton gradient across the inner membrane It prevents pyruvate transport across the outer mitochondrial membrane into the matrix

Correct Answer:

It dissipates the inner membrane proton electrochemical gradient, stimulating electron transport while halting ATP synthesis
