cells need oxygen to help burn the energy in food because the oxygen can take out all the energy needed
Oxygen is the thing that is needed for energy-releasing chemical reactions to talke place inside your body.
The Mitochondria.
The mitochondria
ATP - Adenosine triphosphate
herat
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Yes, it is true.
Thousands of chemical reactions take place in an organism.

ENERGY
Protons are found inside the nucleus of an atom and requires very high energy for nuclear reactions. Chemical reactions generally involve the valence electrons.
Yes, it is true.
The path of chemical energy from the sun starts when the light energy of the sun is converted to glucose in a plant through photosynthesis. The fish then eats the plant matter and its cells perform cellular respiration, breaking down the glucose and releasing the chemical energy inside.
Thousands of chemical reactions take place in an organism.
When two molecules react within a cell, their atoms are rearranged. This releases or consumes energy.
metabolism
Enzymes speed up chemical reactions inside living organisms. They are made up of proteins.
