Respiration

What Is respiration?
A chemical reaction which takes place in all living organisms.
1 of 19
Why do we need energy?
To grow, to keep warm, for movement, for repair.
2 of 19
What is the word equation for respiration?
glucose + oxygen >>> water + carbon dioxide
3 of 19
Where does respiration occur?
In the Mitochondria, they produce and then release glucose and energy.
4 of 19
What does insulin do?
Regulate blood glucose levels.
5 of 19
How and where is glucose stored?
Glucose is stored as glycogen in the muscles and liver.
6 of 19
Why is a higher level of oxygen needed after exercise?
To break down lactic acid.
7 of 19
What is the amount of oxygen needed after exercise called?
The oxygen debt.
8 of 19
What is the word equation for the breaking down of lactic acid?
lactic acid + oxygen >>> carbon dioxide + water
9 of 19
What is the word equation for anaerobic respiration in plants and yeast?
glucose >>> ethanol + carbon dioxide
10 of 19
How do you balance the equation for photosynthesis and respiration?
By putting a 6 in front of water, oxygen and carbon dioxide.
11 of 19
Why would someone still be breathing heavily after exercise?
To remove extra carbon dioxide, repay the oxygen debt, remove heat and start performing aerobic respiration again.
12 of 19
What are lipids?
Lipids are fats and oils.
13 of 19
What are lipids used for?
They are components of cell membranes, energy stores, chemical messengers (hormones) and they are used for protection, water proofing, buoyancy aids and insulation.
14 of 19
How are aerobic respiration chemical reactions controlled?
They are controlled by enzymes.
15 of 19
What makes up a large portion of our cells, muscles and tissues?
Amino acids.
16 of 19
What do amino acids do?
They give cells their structure, build and repair tissues, make antibodies and make hormones.
17 of 19
What is glucose an example of?
A monosaccharide.
18 of 19
What do organisms combine together to make?
Polysaccharides such as cellulose, glycogen and starch.
