Respiration

Question 1

What is the balanced symbol equation for aerobic respiration?

Answer 1

C₆H₁₂O₆ + 6O₂ -> 6CO₂ + 6H₂O + ATP

Question 2

Is energy produced or released?

Answer 2

RELEASED

Question 3

Where does respiration take place in a cell?

Answer 3

The mitochondria

Question 4

What is one characteristic of mitochondria?

Answer 4

They have a large SA/V ratio

Question 5

What are two examples of cells that have lots of mitochondria?

Answer 5

Sperm and muscle cells

Question 6

Effects of exercise on respiration

Answer 6

• breathing rate increases
• depth of breath increases
• heart rate increases 
- increases blood flow to muscles
- more oxygen and glucose delivered - allows increase in respiration + this increase in energy release
• feeling hotter

Question 7

What is the anaerobic respiration?

Answer 7

Respiration in the absence of

oxygen

Question 8

What is the word equation for anaerobic respiration?

Answer 8

glucose -> lactic acid + energy

Question 9

What is the balanced symbol equation for anaerobic respiration?

Answer 9

C₆H₁₂O₆ -> 2C₃H₆O₃ + ATP

Question 10

What is oxygen debt?

Answer 10

The additional oxygen that must be taken into the body after vigorous exercise to restore all systems to their normal states

Question 11

Repaying the oxygen debt

Answer 11

• oxygen needed to break down the lactic acid

lactic acid + oxygen -> carbon dioxide + water
C₃H₆O₃ + 3O₂ -> 3CO₂ +36H₂O

Question 12

What is the word equation for aerobic respiration?

Answer 12

glucose + oxygen -> carbon dioxide + water + energy
