3. All the dinosaurs, along with 50% of all species alive at the time died out when an asteroid struck Earth.
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
3. cell wall
The cell wall is a rigid supporting structure.
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. ... The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
