Question

Identify the types and numbers of molecules that provide the free energy necessary for the reduction of the PGA molecules.

Answer 1

ATP and NADPH

Step-by-step explanation:

The types of molecules that provide the free energy necessary for the reduction of the PGA molecules are ATP and NADPH. ATP is the energy-carrying molecule that provides energy for a wide range of metabolic processes, while NADPH is a coenzyme responsible for providing electrons to metabolic pathways. The number of ATP molecules required is three, while the number of NADPH molecules needed is two.
