Photosynthesis converts light energy to stored chemical energy. What best describes the role of molecular oxygen (O2) in this process?

• an essential reactant that is used to make sugars

• an optional reactant; its presence speeds up the process

• the main product that stores chemical energy for use by the organism

• a byproduct that is released into the atmosphere

• an intermediate that is neither a reactant nor product

The table shows the amount of energy stored in each molecule in the photosynthesis reaction. Use the data to answer the question. Which statement correctly describes the flow of energy in photosynthesis?

• Photosynthesis releases energy when the reactants rearrange and form the bonds in the products.

• Photosynthesis releases energy when carbon dioxide and water combine to form glucose molecules.

• Photosynthesis stores energy because more energy is stored in glucose than it is in carbon dioxide or water.

• Photosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water.

Which statement best explains the relationship between glucose, cellular respiration, and photosynthesis?

• Photosynthesis uses the glucose produced by cellular respiration to make energy.

• Photosynthesis and cellular respiration are both used to produce glucose and energy.

• Photosynthesis produces the glucose used in cellular respiration to make energy.

• Photosynthesis and cellular respiration both consume glucose to produce energy.

In living organisms, lipids function mainly as:

• Sources of stored energy and transmitters of genetic information

• Sources of stored energy and components of cellular membranes

• Transmitters of genetic information and catalysts of chemical reactions

• Catalysts of chemical reactions and components of cellular membranes

Baby food manufacturers sometimes use proteases in their products. Proteases catalyze the breakdown of the proteins in these foods, making digestion easier for infants. Proteases are which of the following?

• enzyme

• fatty acid

• carbohydrate

• nucleic acid

A student walks to school in the morning when the outside temperature is 60°F. When the same student walks home after school, the outside temperature has dropped to 35°F. In this situation, how is thermal homeostasis maintained?

• The student’s heart rate drops as a negative feedback mechanism to deliver less oxygen to the lungs.

• The student begins to sweat as a positive feedback mechanism to reduce the core body temperature.

• The student begins to shiver as a negative feedback mechanism to increase the core body temperature.

• The student’s breathing rate slows as a positive feedback mechanism to deliver more oxygen to the lungs.
