Respiration

Question 1

What is the word equation for respiration?

Answer 1

Glucose + Oxygen ➡️ CO2 + Water + Energy

Question 2

What are uses of energy in cells?

Answer 2

-Muscle Contraction
-Cell Division
-Protein Synthesis
-Transmission of Nerve Impulses

Question 3

What is used to create ATP

Answer 3

The chemical energy in glucose

Question 4

What is the equation for the build up/ break down of ATP?

Answer 4

ATP ↔️ ADP + Pi
(Energy is released and required)

Question 5

Describe the first stage of Aerobic Respiration

Answer 5

-Occurs in the Cytoplam
-Glucose is broken down into 2x pyruvate
-Enough energy is made to produce 2 ATP
-No oxygen is required

Question 6

Describe the second stage of Aerobic Respiration

Answer 6

-Occurs in the Mitochondria
-Oxygen is REQUIRED!
-The 2x pyruvate and oxygen are broken down into CO2 and water
-Enough energy is made to produce lots of ATP

Question 7

What are the products of fermentation in an animal cell?

Answer 7

2x pyruvate (converts into lactate), 2 ATP

Question 8

What are the products of fermentation in plant and yeast cells?

Answer 8

2x pyruvate, CO2 and ethanol
