Cellular Respiration

24. During cellular respiration glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?

B. chemical energy originally stored in the glucose molecule

28. When animals release heat, the heat can be imaged using infrared video cameras. Infrared video cameras would BEST help researchers study which physiology topic?

B. the relationship between activity and metabolic rate

39. In the human body, cellular respiration breaks down sugar molecules after they enter the cell. What results from this process?

B. release of energy

63. Which is a difference between anaerobic respiration and aerobic respiration?

B.Anaerobic respiration does not require oxygen.

56. Which process releases the highest amount of energy?

B.aerobic respiration

32. An amoeba uses a sugar molecule during metabolic activity. It loses energy to the environment as a result. The transformation of energy from the sugar molecule to environmental energy can be described as a transformation between which of these?

B.chemical energy to thermal energy

47. In a human, which factor would most likely limit the production of ATP through cellular respiration?

D. availability of reactants such as glucose

17. The energy required to lift an object is supplied by ATP derived from the breakdown of molecules of

D. glucose.

69. How are the reactions for photosynthesis and cellular respiration related?

A. The glucose and oxygen produced in photosynthesis are used as reactants in aerobic cellular respiration.

9. Glucose molecules provide the chemical energy cells use to carry on life processes. Some energy is always lost when cells break down the glucose molecules. Which statement explains how energy is lost in this process?

C. Some energy is converted into heat.

1. The products from cellular respiration are used in which other chemical process?

C. photosynthesis

51. How do cells in the human body release energy stored in an adenosine triphosphate molecule (ATP)?

C.by breaking a phosphate bond in ATP
