Respiration

Question 1

What are the 7 uses of energy in the body?

Answer 1

• Protein synthesis
• Active transport
• Growth
• Maintaining a constant internal environment
• Nervous transmission
• Muscle contraction
• Cell division

Question 2

What is respiration?

Answer 2

a series of reaction in the form of using enzymes to obtain energy from molecules at ATP (such as glucose)

Question 3

What aerobic respiration?

Answer 3

Chemical reactions that use oxygen to break down molecules for energy

Question 4

What is the word and symbol equation for aerobic respiration?

Answer 4

Glucose + Oxygen –> Carbon dioxide + water + energy

C6H12O6 + 6O2 ———> 6CO2 + 6H2O + ATP

Question 5

What is anaerobic respiration?

Answer 5

Chemical reactions that break down molecules to release energy without using oxygen

Question 6

What is the word equation for anaerobic respiration?

Answer 6

glucose –> lactic acid + energy

Question 7

What is the word and symbol equation for anaerobic respiration in yeast?

Answer 7

glucose –> alchohol + carbon dioxide + energy

C6H12O6 -> 2C2H5OH + 2CO2 + ATP

Question 8

What builds up in muscles during periods of vigorous exercise and how do you remove it?

Answer 8

Lactic acid, you can remove lactic acid through aerobic respiration in the liver

Question 9

Why are our heart rates increase after exercise?

Answer 9

To move the lactic acid from the blood in our muscles to our liver where we increase the rate of aerobic respiration to remove the lactic acid in the liver
