Axons terminate in a series of fine extensions known as

Correct Answer: A

Rationale: Telodendria are the fine extensions at the end of an axon.

Correct Answer: B

Rationale: triglycerides are used for ATP, insulation, padding, and vitamin absorption, while cholesterol forms hormones, bile salts, and stabilizes membranes ; others mismatch roles.

Correct Answer: B

Rationale: A redox reaction involves oxidation and reduction , as per text; it's not just energy , protein breakdown , or glucose synthesis .

Correct Answer: B

Rationale: The citric acid cycle primarily involves oxidation reactions, where NAD⁺ and FAD are reduced to NADH and FADH₂ as electrons are transferred from substrates, and decarboxylation reactions, where CO₂ is removed (e.g., from isocitrate and α-ketoglutarate). These processes are symbolically indicated by NAD⁺/FAD (for oxidation) and CO₂ (for decarboxylation). Other options mismatch the reactions (e.g., synthesis, hydrolysis, phosphorylation, dehydration) or symbols (e.g., H₂O, O₂, ATP, P) with the cycle’s primary processes.

Correct Answer: B

Rationale: beta oxidation products as Acetyl CoA, NADH + H⁺, and FADH₂ ; not glucose , components , or end products .
