Bioenergetics

How is energy released from ATP?

• By breaking the bond between the first and second phosphate

• By removing the 3rd phosphate

• By converting ATP to ADP without any phosphate removal

• By hydrolyzing the entire ATP molecule

Why is ATP considered the energy currency of the cell?

• ATP is used by cells to store and transfer energy for various cellular processes.

• ATP is a type of protein that helps in cellular respiration.

• ATP is a waste product of cellular metabolism.

• ATP is primarily used for DNA replication.

What is the main purpose of Cellular Respiration?

• To convert food into usable energy (ATP) for the cell.

• To store energy for later use.

• To break down waste products in the cell.

• To synthesize proteins for cellular functions.

What do the explosions in a photo of cellular processes represent?

• ATP

• NADH

• Glucose

• Oxygen

What is the byproduct of fermentation in yeast?

• Ethanol and carbon dioxide.

• Lactic acid and oxygen.

• Glucose and water.

• Acetic acid and nitrogen.

What is the chemical equation for aerobic respiration?

• Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)

• Glucose + Lactic Acid → Carbon Dioxide + Water + Energy (ATP)

• Glucose + Nitrogen → Carbon Dioxide + Water + Energy (ATP)

• Glucose + Sulfur → Carbon Dioxide + Water + Energy (ATP)

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs in the absence of oxygen, while anaerobic respiration requires oxygen.

• Anaerobic respiration generates more ATP than aerobic respiration.

• Less ATP is generated during anaerobic respiration than during aerobic respiration.

• Aerobic respiration is faster than anaerobic respiration.

What is Fermentation?

• A process that requires no oxygen and produces a minimal amount of ATP.

• A process that requires oxygen and produces a large amount of ATP.

• A process that occurs only in plants and produces glucose.

• A process that occurs in the presence of light and produces energy.

What is the significance of glucose in cellular respiration?

• Glucose is the primary fuel source for cellular respiration.

• Glucose is a byproduct of cellular respiration.

• Glucose is used to store energy in the form of starch.

• Glucose is not involved in cellular respiration.

What is Cellular Respiration?

• A process by which cells use oxygen to produce energy from food.

• A method of photosynthesis in plants.

• A way for cells to reproduce and divide.

• A technique for storing energy in the form of fat.
