'Where within the cell is the majority of ATP produced?

• cytoplasm

• mitochondria

• endoplasmic reticulum

: Which energy association is correct?

• Water stored behind a dam is an example of kinetic energy.

• Light energy is a form of chemical energy

• Kinetic energy is energy of motion.

Occasionally someone claims to have built a machine that can run forever, producing as much energy as it consumes. This has always been disproved because it violates

• the first law of thermodynamics.

• the second law of thermodynamics.

• coupled reaction equations.

Heat

• is an unusable form of energy.

• is not a form of energy.

• is a usable form of energy.

Which of the following is not a cellular function of ATP?

• chemical work

• adding structural integrity to the cell membrane

• moving substances into a cell

During cellular respiration, what is reduced?

• Oxygen

• Water

• Carbon dioxide

Chemical reactions that require an input of energy are

• coupled reactions.

• exergonic reactions.

• endergonic reactions.

A reaction that is "endergonic, anabolic, nonspontaneous, and has a positive delta G" could be describing

• a reduction reaction.

• a coupled reaction.

• photosynthesis.

Chloroplasts and mitochondria are both involved in redox reactions because

• photosynthesis uses energy and cellular respiration releases energy.

• energy cycles between the two organelles.

• carbon dioxide is reduced during photosynthesis and carbohydrates are oxidized during cellular respiration.

Poisons are often

• cofactors.

• kinases.

• enzyme inhibitors.
