Biology Unit 2.6 - Aerboic, and Anaerobic Respiration

HideShow resource information
Define respiration:
Respiration is the process of releasing energy from glucose, which happens constantly in every cell.
1 of 22
What type of respiration requires oxygen?
Aerobic respiration.
2 of 22
What is the word equation for aerobic respiration?
Glucose + Oxygen -> Carbon Dioxide + Water (+Energy Released)
3 of 22
What type of energy does ATP carry?
Energy that has been released during respiration.
4 of 22
What is an ATP?
A small molecule that's easily transported around cells.
5 of 22
What type of respiration(s) produces ATP?
Aerobic and anaerobic.
6 of 22
What type of respiration are we using most of the time?
Aerobic.
7 of 22
ATP is synthesised from another molecule called....
ADP.
8 of 22
In anaerobic Respiration, what happens to the glucose?
It is partially broken down.
9 of 22
What is the normal resting heart rate range for an adult?
60-80 beats/min.
10 of 22
Pulse Rate is a measure of _____ rate.
Heart
11 of 22
When heart rate increases, the pressure of _____ increases.
Blood.
12 of 22
When the heart relaxes, the pressure is at its lowest - this is the...
Diastolic pressure.
13 of 22
The Blood Pressure is at its Highest when the Heart Contracts - this is the....
Systolic pressure.
14 of 22
What is the word equation for Anaerobic Respiration?
Glucose -> Lactic Acid (+ Energy Released).
15 of 22
What is the symbol equation for aerobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
16 of 22
Where do most reactions for aerobic respiration take place?
Mitrchondria.
17 of 22
How may energy from respiration be used?
To build larger molecules from smaller ones in animals. To enable muscles to contract in mammals and birds. To maintain a steady body temperature in colder surroundings in plants. To build up sugars, nitrates and other nutrients into amino acids.
18 of 22
Describe the changes during exercise.
The heart rate increases. The rate and depth of breathing increases.
19 of 22
What do these changes during exercise result in?
Increase the blood flow to the muscles and so increase the supply of sugar and oxygen and increase the rate of removal of carbon dioxide.
20 of 22
Muscles store glucose as glycogen, which can then be converted back to glucose for use during exercise.

What happens to theoxygen debt?
Anaerobic respiration results in an oxygen debt that has to be repaid in order to oxidise lactic acid to carbon dioxide and water.
