What are the two main products of the Krebs Cycle?

• H₂O and CO₂

• ATP and CO₂

• ATP and O₂

• ADP and H₂O

Answer explanation

The two main products of the Krebs Cycle are ATP and CO2. ATP is the energy currency of the cell, while CO2 is a waste product of cellular respiration.

How would you describe cellular respiration?

• Sunlight and CO₂ make ATP

• ATP and O₂ are used to make sugars

• Carbon-based molecules from food and oxygen are used to make ATP

• ATP and CO₂ are used to make ADP and Water

Answer explanation

Cellular respiration is the process where carbon-based molecules from food and oxygen are used to make ATP, the energy currency of cells.

Which organisms perform CELLULAR RESPIRATION?

• Only Autotrophs

• Only Heterotrophs

• Autotrophs and Heterotrophs

Answer explanation

Both autotrophs and heterotrophs perform cellular respiration. Autotrophs produce their own food through photosynthesis, while heterotrophs obtain food by consuming other organisms.

Which of the following is NOT a stage of cellular respiration?

• Glycolysis

• Fermentation

• Krebs cycle

• Electron transport

Answer explanation

Fermentation is not a stage of cellular respiration. It is an alternative pathway for ATP production in the absence of oxygen.
