Germinating plant seeds can convert acetyl-CoA (obtained from fatty acids stored as oils)into carbohydrates,whereas animals are incapable of converting fatty acids into glucose.This difference is due to the fact that:

Question

Quizplus · Accepted Answer

The glyoxylate cycle is a metabolic pathway used by plants and some bacteria to convert two acetyl CoA to oxaloacetate, a precursor for gluconeogenesis. This allows plants to convert fatty acids into carbohydrates, which is not possible for animals. Option A is not correct since the presence of glycogen does not explain why animals cannot convert fatty acids into glucose. Option C is not correct since germinating plant seeds may not have access to sunlight for photosynthesis. Option D is also incorrect because both plants and animals use the citric acid cycle for energy production, and plants use glycolysis as well. Option E is partially correct, but Option B provides a more complete explanation.
