Description of reaction
Chemical reaction that Chemical reaction that
requires energy, do not releases energy, tend to
proceed spontaneously proceed spontaneously
Example of reaction
Photosynthesis Cellular respiration
What is activation energy and why is important to understand activation energy in Biology?
Heat cannot be used to speed up chemical reactions in the body as
it would kill the organism (ex: by denaturing critical proteins).
Therefore, in order for reactions to occur, the activation energy
barrier of biological reactants must be overcome by the use of
Explain why the hydrolysis of the 3rd phosphate on an ATP molecule releases energy (feel free to use a
diagram to help you)
The bond between the terminal and the second phosphate of ATP
is high energy.
This is because the phosphate
