Answer:
I definitely think that is plant, I am not sure about the other ones
The option that u have selected is perfectly right.
Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.
The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.
The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

The ultimate source of energy for living things is the Sun. Plants and other photosynthetic organisms take the energy from sunlight to make glucose. This energy passes to other organisms through the food chain.
