mitochondria
Photolysis occurs in the light-dependent reactions of photosynthesis. These reactions include the light absorption by chlorophyll, splitting of water into oxygen and protons, and the generation of ATP and NADPH.
Nuclear reactions
No, radiation occurs mainly between gases!
Chemical change occurs
Mainly in stars, although some is seen in the secondary of a thermonuclear weapon.
Heat and helium mainly
New Zealand
It occurs mainly in Southeast Asia
Mainly floods and droughts.
In "Decomposition" type of reactions, one chemical compound would split to form two or more chemical compounds. These reactions mainly occur with the supply of heat. For example: CaCO3 -----> CaO + CO2 The opposite of this, that is when many chemical compounds form one are known as "Synthesis / Combination" type of reactions.
The place where light reactions occurs are the grana. These are composed of thylakoid sacs that are stacked and embedded in the chloroplast.
The Calvin cycle occurs at any time of the day, while the light dependent reactions require light. The calvin cycle produces glucose, while the light dependent reactions produce oxygen, ATP, and NADPH. The calvin cycle occurs because of the products of the light dependent reactions.
