Question

5 most electron carriers are ______ multiple choice hydrogens enzymes inorganic phosphates polysaccharides coenzymes

Explanation:

Electron - carriers are often coenzymes. Coenzymes like NAD+ and FAD can accept and donate electrons during metabolic reactions. Hydrogens are not electron - carriers themselves in the context of metabolic electron - transfer. Enzymes are biological catalysts and not electron - carriers. Inorganic phosphates are involved in energy - related processes like ATP synthesis but not as electron - carriers. Polysaccharides are carbohydrates mainly used for energy storage or structural purposes and not for electron - transfer.

Answer:

E. coenzymes
