1
Q
In humans what is the source of the organic compounds broken down in cell respiration?
A
The food we eat
2
Q
How is ATP made?
A
A phosphate group is linked to adenosine diphosphate- energy is required for this reaction, it comes from the breakdown of organic compounds
3
Q
What are the main types of cell activities that require energy?
A
1) synthesising large molecules like DNA , RNA and proteins
2) pumping molecules or ions across membranes by active transport
3) moving things around the inside of the cell, such as chromosomes etc
4
Q
What is the advantage of ATP
A
As an energy supply is it immediately available- released simply by splitting ATP and ADP and phosphate
5
Q
When is glucose broken down and what is the yield of ATP?
A
Glucose is broken down in anaerobic respiration without using oxygen😝 yield of ATP is very small but it can be produced quickly
6
Q
What is the 3 useful situations of anaerobic respiration?
A
1) when short but rapid burst of ATP production is needed
2) when oxygen supplies run out in respiration cells
3) in environments that are deficient in oxygen
7
Q
What is the product of anaerobic respiration in humans?
A
Lactic acid then to lactate
8
Q
Anaerobic respiration is used I yeast which produces what?
A
Ethanol and carbon dioxide- yeast converts sugars into ethanol in large fermenters by anaerobic respiration - the ethanol produced by the yeast is purified by distillation and then used as petrol
9
Q
Lactate production in humans when anaerobic respiration is used does what?
A
Maximises the power of muscle contractions
10
Q
What does aerobic respiration require and what does it produce?
A
Requires oxygen and gives a large yield of ATP from glucose
11
Q
What is the formula?
A
Glucose + oxygen --> carbon dioxide + water
12
Q
What is cell respiration?
A
The controlled release of energy from organic compounds to produce ATP
