Unit 1: Energy Systems

Question 1

What is respiration? What are the two types of respiration?

Answer 1

Respiration - when the body makes energy (ATP) it can use to perform tasks eg muscles contracting

Aerobic - energy made with oxygen
Anaerobic - energy made without oxygen

Question 2

What is ATP?

Answer 2

ATP = adenosine tri-phosphate

Form of energy stored in the body

Question 3

What does resynthesis of energy mean?

Answer 3

Body making more energy (ATP) through respiration.

Question 4

What is anaerobic respiration?

Answer 4

Producing energy (ATP) without the presence of oxygen

Question 5

What is aerobic respiration?

Answer 5

Producing energy (ATP) with oxygen

Question 6

What is the equation for anaerobic respiration?

Answer 6

glucose = lactic acid + energy (ATP)

Question 7

What is the equation for aerobic respiration?

Answer 7

glucose + oxygen = carbon dioxide + water + energy (ATP)

Question 8

What is lactic acid?

Answer 8

Waste product of anaerobic respiration that causes cramps/fatigue in the muscles

Question 9

How long does anaerobic respiration provide us with energy (ATP) for?

Answer 9

1-60 secs of high intensity effort

Question 10

How long does aerobic respiration provide us with energy (ATP) for?

Answer 10

1min-several hours of medium/low intensity effort
