What is Respiration?
It's the process of releasing energy from glucose. Respiration goes on in every cell in your body.
1 of 21
What does ATP do?
It acts as the energy source for many cell processes and transports energy to where it is needed in a cell.
2 of 21
What is Respration controlled by and what does it mean?
Enzymes. This means that the rate of respiration is affected by both temperature and pH.
3 of 21
What two types of respiration are there?
Aerobic and Anaerobic.
4 of 21
What does Aerobic Respiration need?
It needs plenty of oxygen.
5 of 21
Which type of Respiration are we using most of the time?
Aerobic respiration.
6 of 21
The word and chemical equations for Aerobic Respiration?
glucose + oxygen -> carbon dioxide + water (+ energy).
7 of 21
What is the Metabolic rate?
The amount of energy used.
8 of 21
What does Anaerobic Respiration use?
It doesnt use oxygen at all.
9 of 21
When is Anaerobic Respiration used and why?
It is used when you do extreme exercise because your body can't supply enough oxygen to your muscles for aerobic respiration.
10 of 21
Which type of respiration is the most efficient to release energy from gluecose and why?
Aerobic because anaerobic releases much less energy per glucose molecule than aerobic.
11 of 21
Which type of respiration causes the glucose to only be partically broken down?
Anaerobic respiration.
12 of 21
When is lactic acid produced and what does it do?
It is produced because the glucose is only partically broken down. The lactic acid builds up in the muscles, which gets painful and makes your muscles fatigued.
13 of 21
Anaerobic respiration word equation?
Glucose + Lactic Acid (+ energy)
14 of 21
What is an advantage of using Anaerobic Resipration?
The advantage is that you can keep on using your muscles.
15 of 21
What happens to Anaerobic respiration when you stop exercising?
When you stop exercising you'll have an oxygen debt. You need extra oxygen to break down all the lactic acid thats built up in ypur muscles and to allow aerobic respiration to begin again.
16 of 21
How do you repay the oxygen debt?
You have to keep breathing hard for a while after you stop exercising to repay the debt.
17 of 21
What has to happen to the lactic acid?
It has to be carried to the liver to be broken down so your heart rate has to stay high too.
18 of 21
What can the Respiratory Quotient (RQ) tell?
It can tell you whether someone is repiring aerobically or Anaerobically.
19 of 21
What is the RQ equation?
RQ= Amount of CO2 produced / Amount of o2 used
20 of 21
How do you know what is anaerobic and aerobic respiraton when using the RQ?
RQ is usually between 0.7 and 1 - this means that the person is respiring aerobically. If the RQ value is greater than 1 then the person is short of oxygen and is respiring anaerobically, too
