Question

enzymes

1. in the chemical equation label the reactants and products.

6 co₂ + 6 h₂o → c₆h₁₂o₆ + 6o₂

1. label where substrate, enzyme, product(s), reactant, lock and key fit, and active site are on the following diagram:
2. what is activation energy?

a. what role do enzymes play regarding activation energy?

1. using the graph, what is the temperature required for maximum enzyme effectiveness?
2. using the graph, what will happen to the enzyme’s effectiveness if the solution is heated 55°c?

a). why?

Step1: Identify reactants

Reactants are on the left - hand side of the chemical equation. So, the reactants are $6CO_2$ and $6H_2O$.

Step2: Identify products

Products are on the right - hand side of the chemical equation. So, the products are $C_6H_{12}O_6$ and $6O_2$.

The large, irregular - shaped structure is the enzyme. The smaller structure that fits into the enzyme is the substrate. The result of the reaction is the product. Reactants are the starting substances (substrate is a type of reactant in enzyme - catalyzed reactions). The lock and key fit refers to the specific interaction between the enzyme's active site (the pocket or groove on the enzyme) and the substrate.

Activation energy is the minimum amount of energy that reacting molecules must have to undergo a chemical reaction. Enzymes lower the activation energy of a chemical reaction, making the reaction occur more readily.

Answer:

Reactants: $6CO_2$ and $6H_2O$; Products: $C_6H_{12}O_6$ and $6O_2$
