Respiration

?
What is respiration?
Respiration is the process of releasing energy from glucose. The energy produced cannot be used by cells directly, and so the cells instead use ATP. ATP is used in many cell processes and transports energy to where it is needed in the cell.

What are the two types of respiration?
The two types of respiration are aerobic and anaerobic. Aerobic respiration needs plenty of oxygen, whereas anaerobic respiration doesn't need any oxygen at all.

What is respiration controlled by?
Respiration is controlled by enzymes, meaning the rate of respiration is controlled by pH and temperature.

What is the equation for aerobic respiration?
glucose + oxygen → carbon dioxide + water (+ energy) / C(6)H(12)O(6) + 6O(2) → 6CO(2) + 6H(2)O (+ energy)
4 of 13
What is the equation for anaerobic respiration?
glucose → lactic acid (+ energy)

What is aerobic respiration?
This type of respiration is the most effective and it is the type of respiration that you are using most of the time. When the rate of respiration increases, the oxygen consumption and carbon dioxide production increases.

What is aerobic respiration?
This means that the oxygen consumption can be used to estimate the metabolic rate (the amount of energy used).

What is anaerobic respiration?
When you do really vigorous exercise, your body can't supply enough oxygen for aerobic respiration to occur - even though your heart rate and breathing rate increase as much as they can.

What is anaerobic respiration?
Anaerobic respiration produces a lot less energy per glucose molecule than aerobic respiration. When you are respiring anaerobically, glucose is only partially broken down and lactic acid builds up in your muscles, causing muscle fatigue.

What is anaerobic respiration?
After resorting to anaerobic respiration, when you stop exercising you'll have an oxygen debt. This means you need extra oxygen to break down the lactic acid and to get aerobic respiration to occur again.

What is anaerobic respiration?
You'll have to start breathing heavily for a while. The lactic acid is taken to the lungs to be broken down, meaning your heart rate will stay high too.

The Respiatory Quotient
(RQ = CO(2) produced ÷ O(2) used) The respiatory quotient can tell you whether someone is respiring aerobically or anaerobically.
12 of 13
The Respiatory Quotient
If the RQ is between 0.7 and 1, then the person is respiring aerobically, whereas if it is greater than 1, then the person is short of oxygen and is respiring anaerobically.
