CONNECT CH11 CATABOLISM REVIEW

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
