Question

7 multiple choice 1 point in order for a chemical reaction to occur, an input of energy is required, which is referred to as the activation energy enzyme product active site 8 multiple choice 1 point to extract catalase from potatoes, you will be homogenizing potato pieces using a centrifuge blender french press refrigerator.

Explanation:

For question 7, activation energy is the minimum energy required for a chemical reaction to start. Enzymes are biological catalysts, products are the substances formed in a reaction, and an active - site is part of an enzyme where the substrate binds.
For question 8, a blender is commonly used to homogenize potato pieces to extract catalase. A centrifuge separates components by density, a French press is for coffee - making and not for homogenization in this context, and a refrigerator is for cooling and not for homogenization.

Answer:

1. A. activation energy
2. B. blender
