Which of the following descriptions explains the process of cellular respiration?

• Solar energy is absorbed by the chloroplasts and placed into the bonds of glucose

• Excess energy from glucose molecules is used to synthesize new lipid molecules

• Energy is removed from food molecules like glucose and placed into the bonds of ATP

• Disaccharides are attached to protein molecules which are then packaged into vesicles

Which of the following descriptions explains the process of photosynthesis?

• Oxygen is used to remove the energy from glucose so that it can be placed into ATP

• The energy from food molecules is released in the absence of oxygen gas

• Energy from inorganic compounds is used to synthesize carbohydrates molecules

• Energy in the form of light is absorbed and converted into the chemical energy in glucose

Excess energy from molecules of glucose is often used to synthesize new triglyceride (fat) molecules through the process of lipogenesis. What is the primary reason for performing this conversion?

• Lipogenesis allows cells to be motile

• Fats store energy more efficiently than glucose

• Glucose molecules cannot be kept in the cell
