what is the chemical equation formula for photosynthesis?
6CO2+6H20--->C6H12O6+6O2
2 of 26
is photosynthesis an endothermic or exothermic reaction?
endothermic reaction in which energy is transferred from the environment to the chloroplasts (by light)
3 of 26
Name the four factors that affect the rate of photosynthesis (also known as limiting factors)
Light intensity, carbon dioxide concentration, Temperature, amount of chlorophyll present in the leaf.
4 of 26
Name the 5 things that plants use glucose for after it is produced during photosynthesis?
Used for resperation, converted into insoluble starch for storage, used to produce fat or oil for storage,used to produce cellulose, which strengthens the cell wall and used to produce amino acids for protein synthesis
5 of 26
What do plants use to produce protein?
Nitrate ions that are absorbed from the soil
6 of 26
Where does respiration take place
in cells
7 of 26
In respiration an endothermic or exothermic reaction?
It is a exothermic reaction which is continuously occurring in living cells
8 of 26
What is the name of respiration when oxygen is present?
Aerobic resperation
9 of 26
What is the name of respiration when oxygen is NOT present?
Anaerobic respirtation
10 of 26
what do organisms use energy from respiration for?
chemical reactions to build larger molecules, movement and keeping warm
11 of 26
what is the word equation for aerobic respiration?

what is the word equation for anaerobic respiration in muscles?
glucose-->lactic acid
14 of 26
which releases greater amounts of energy?
aerobic respiration
15 of 26
what is the word equation for the anaerobic respiration in plants and yeast
glucose-->ethanol+carbon dioxide
16 of 26
what is the name used to describe anaerobic respiration in plants and yeast?
fermentation
17 of 26
what industries are fermentation important in ?
in the bread and alcohol production industries
18 of 26
when will the body need to increase its demand for oxygen?
during exercise
19 of 26
what does the body do to supply more oxygenated blood to the muscles
the heart rate,breathing rate and breath volume increase
20 of 26
what happens if not enough oxygen is present in the muscles
anaerobic respiration takes place
21 of 26
what does the incomplete oxidation of glucose lead to during this type of respiration?
a build up of lactic acid which creates an oxygen dept
22 of 26
what happens to your muscles after long periods of intense activity?
muscles become fatigued and stop contracting efficiently
23 of 26
what is metabolism
the sum of all the reactions in a cell or the body
24 of 26
name examples of metabolism in the body?
conversion of glucose to starch, glycogen and cellulose, the formation of lipid molecules from a molecule of glycerol and three molecules of fatty acids.....
25 of 26
Carried on
the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins, respiration, breakdown of excess proteins to from urea for excretion
