Option B.
Thiamine pyrophosphate.
Explanation:
Pyruvate dehydrogenase is an enzyme that catalyses the oxidative decarboxylation of pyruvate to acetyl coA , NADH and CO2. Pyruvate dehydrogenase uses NAD, biotin, FAD and lipoic acid.
Thiamine pyrophosphate is not a cofactor for pyruvate dehydrogenase . It is a cofactor in living systems. Thiamine pyrophosphate is a coenzyme that function in carbohydrates, Amino acids and lipids metabolism.
Ответ:
the answer for PLATO is:
"Yes, because these organisms likely depend on each other for survival. For example, plants and grasses can make food for insects and other small animals, such as rats. Carnivores can eat the small animals and obtain energy from them. Humans are also living things, sk they contribute to the ecosystems of these organisms. They can provide food for rats and insects. Humans can also water the plants"
Paraphrase that as you will.
