The plasma membrane is a selectively permeable structure that encloses cell contents; all materials entering or leaving a cell must pass through this structure.

• True

• False

What concentration gradient does a Na+/K+ pump establish?

• High concentration of K+ inside the cell/Low concentration of K+ outside the cell

• High concentration of K+ inside the cell/High concentration of Na+ outside the cell

• High K+ and Na+ inside the cell

• High K+ and Na+ outside the cell

Answer explanation

K+/Na+ pump will utilize ATP to energize transport of 2 K+ into the cell and  3 Na+ out of the cell.

What is the main goal of Aerobic Cellular Respiration?

• To pass/diffuse solvents through a semipermeable membrane

• Transforming energy in 1 glucose molecule to ~36 ATP

• Transforming energy in 2 glucose molecules to ~36 ATP

What are two organelles found in both plant and animal cells?

What does Glycolysis produce?

• ATP

• ATP, 2 Pyruvate, 2 NADH

Which stage of cellular respiration produces the most ATP?

• Glycolysis

• Electron Transport Chain & Chemiosmosis (Oxidative Phosphorylation)

• Citric Acid/Kreb's Cycle

• Transition Reaction

Answer explanation

This step produces ~26-28 ATP.

What are some structures that distinguish a plant cell?

• Cell Wall

• Central Vacuole

• Nucleus

• Chloroplast

• True

• False

Enzymes can make non-spontaneous reactions spontaneous.

• True

• False
