Metabolic Pathways

Question 1

is the anaerobic breakdown of glucose into pyruvate, yielding 2 ATP and 2 NADH, occurring in the cytoplasm.

Answer 1

Glycolysis

Question 2

Each pyruvate (converted to Acetyl-CoA) enters the mitochondrial matrix. Produces ATP, NADH, FADH₂, and CO₂ as waste. Is a aerobic process

Answer 2

Krebs Cycle

Question 3

Involves the transfer of electrons through a series of complexes in the inner mitochondrial membrane. Generates a proton gradient, leading to ATP synthesis via oxidative phosphorylation. Oxygen is the final electron acceptor, combining with protons to form water.

Answer 3

Electron transport chain

Question 4

are a series of chemical reactions that occur within a cell to maintain life. These reactions are carefully regulated and catalyzed by enzymes to ensure efficiency and control.

Answer 4

Metabolic pathways

Question 5

Pathways that break down large molecules into smaller ones, releasing energy that is captured in molecules like ATP and NADH.

Answer 5

Catabolic pathway

Question 6

Pathways that synthesize larger molecules from smaller ones, requiring an input of energy, often in the form of ATP or NADPH.

Answer 6

Anabolic pathway

Question 7

The main energy currency in cells. Energy is released when ATP is hydrolyzed to ADP (Adenosine Diphosphate) + inorganic phosphate.

Answer 7

ATP (Adenosine Triphosphate)

Question 8

Electron carriers that store energy by transporting high-energy electrons to the electron transport chain.

Answer 8

NADH AND FDH2
