Answer: The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy.
A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.
The two stages of photosynthesis represented by B and C are the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, light energy is used to produce ATP and NADPH. These energy carriers are then used in the Calvin cycle to convert CO₂ into glucose.
The two stages of photosynthesis represented by B and C in the diagram are the light-dependent reactions and the Calvin cycle.
In the light-dependent reactions, chlorophyll absorbs light energy and uses it to produce ATP and NADPH. These energy-carrying molecules are then used in the Calvin cycle, which takes place in the stroma. In the Calvin cycle, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.
