Introduction to Respiration (4.4.1)

HideShow resource information
What is the purpose of respiration in cells?
To release energy from organic molecules such a glucose, in the form of ATP, which can then be used to drive active processes in cells.
1 of 7
What is the equation for respiration?
C6H12O6 + 6O2 --> 6H2O + 6CO2
2 of 7
Name3 metabolic processes that require ATP energy?
Active transport- moving molecules across membrane against the conc. gradient. Secretion of substances from cells. Endocytosis- bulk movement of substances into cells.
3 of 7
What does ATP stand for?
Adenosine Tri Phosphate.
4 of 7
How much energy is released when one phosphate group is removed from ATP?
30.5kJ.
5 of 7
Why do we use ATP for energy instead of glucose?
The amount of energy released when ATP is broken down is a suitable amount to drive individual reactions. Energy from ATP can be released quickly and easily.

What are the four stages of respiration?
Glycolysis. Link Reaction. Krebs Cycle. Oxidative Phosphorelation.
