To get the most ATP molecules for energy in cellular respiration, you have to have lots of ?

hydrogen

oxygen

carbon dioxide

water

The waste gas given off by cellular respiration is?

oxygen

carbon dioxide

nitrogen

methane

What is the correct equation for cellular respiration?

oxygen + sugar -> carbon dioxide + water + Energy

carbon dioxide + sugar + Energy -> carbon dioxide + water

carbon dioxide + water -> oxygen + sugar + Energy

carbon dioxide+ water + Energy -> oxygen + sugar

10.

What is important about cellular respiration?

It produces energy from the sun.

It forms sugar.

It transforms sugar into a usable form of energy (ATP)

Only plants perform this process.

11.

What happens to your breathing rate when you exercise?

It increases

It decreases

It stays the same

12.

One molecule needed for cellular respiration is

carbon dioxide

glucose

water

chlorophyll

13.

One molecule produced by animals during cellular respiration is

carbon dioxide

glucose

oxygen

chlorophyll

14.

Which of the following structure is where cellular respiration (Kreb's Cycle and Electron Transport Chain) occurs in the cell?

nucleus

cytoplasm

mitochondria

vacuoles

15.

What is the correct equation for cellular respiration?

6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

6CO₂+ 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

16.
