Enzymes increase activation energy by destabilizing the transition state.

Enzymes have no effect on the activation energy of reactions.

Enzymes only work at high temperatures to lower activation energy.

Enzymes lower activation energy by stabilizing the transition state and providing an alternative reaction pathway.

Cellular respiration occurs only in the presence of sunlight.

Cellular respiration is the breakdown of proteins into amino acids.

Cellular respiration is the process of converting glucose and oxygen into energy, and it is important because it provides the energy required for all cellular activities.

Cellular respiration is the process of photosynthesis in plants.

Krebs Cycle, Lactic Acid Cycle, Oxidative Phosphorylation

Glycolysis, Photosynthesis, Citric Acid Cycle

Fermentation, Calvin Cycle, Light Reactions

Glycolysis, Krebs Cycle, Electron Transport Chain

Both aerobic and anaerobic respiration require oxygen to function.

Anaerobic respiration produces more energy than aerobic respiration.

Aerobic respiration occurs only in plants, while anaerobic respiration occurs in animals.

Aerobic respiration uses oxygen and produces more energy, while anaerobic respiration does not use oxygen and produces less energy.

ATP is a lipid that stores genetic information.

ATP is a type of protein that helps in muscle contraction.

ATP is adenosine triphosphate, and it is called the energy currency of the cell because it stores and provides energy for cellular processes.

ATP is a sugar molecule that provides structural support to cells.

Glycolysis generates FADH2; the Krebs cycle produces only ATP.

Glycolysis produces ATP and NADH; the Krebs cycle generates NADH and FADH2 for ATP production.

Glycolysis and the Krebs cycle are both anaerobic processes that do not require oxygen.

Glycolysis only produces glucose; the Krebs cycle does not produce any energy.

Oxygen is essential for aerobic respiration as it accepts electrons and helps produce ATP.

Oxygen is used to break down glucose into lactic acid.

Oxygen is a byproduct of cellular respiration.

Oxygen is only needed for anaerobic respiration.

Cellular respiration occurs without any enzymes.

Enzymes are only involved in digestion, not metabolism.

Enzymes speed up the metabolic reactions involved in cellular respiration, which converts energy for cellular use.

Metabolism does not involve energy conversion processes.
