Cellular Respiration/photosynthesis review

Does cellular respiration store or release energy?

• Store

• Release

Energy is produced during cellular respiration and stored in the form of ______.

• APT

• ATP

• TPA

• PTA

Answer explanation

ATP (Adenosine Triphosphate) is the body's currency for energy. It is the main output of cellular respiration.

Which organelle does cellular respiration happen in?

• Nucleus

• Mitochondria

• Chlorophyll

• Chloroplast

Cellular respiration is...

• the process by which cells break down glucose into energy. 
• the process by which cells break light down into energy. 
• the process by which cells communicate with other cells. 

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

Which organisms perform CELLULAR RESPIRATION?

• Only Autotrophs
• Only Heterotrophs
• Autotrophs and Heterotrophs

Which step of aerobic cellular respiration makes the most ATP?

• Glycolysis
• Krebs Cycle
• Electron Transport Chain
• Light Dependent Reactions

Glycolysis breaks down glucose into 2 molecules of
