Although sources of energy, electrons, and carbon are diverse, all are used to generate which three main products?

ATP reducing power precursor metabolites

In both aerobic and anaerobic respiration, _ is synthesized from ADP and phosphate, using a type of potential energy called the _ motive force.

ATP proton

Choose any that are correct statements about fermentation.

ATP is synthesized by substrate-level phosphorylation. It does not involve an electron transport chain. Pyruvate is a common electron acceptor used.

In general terms, the two sources of energy available for organisms are certain chemicals (e.g., carbohydrates, proteins, and fats) and

light or sunlight
