Which of the following descriptions explains the process of cellular respiration?​ (a)   ​

• 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
• 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
