Introduction: Glycolysis is the process of breakdown of glucose. The resultant product is the pyruvate along with the release of two molecules of ATP. Gluconeogenesis is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon sources.

(b)

Summary Introduction

To determine: The true statement for the given false statement, “because glycolysis involves the partial oxidation of glucose, it cannot proceed in the absence of oxygen”.

Introduction: Glycolysis is the process of breakdown of glucose. The resultant product is the pyruvate along with the release of two molecules of ATP. Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism.

(c)

Summary Introduction

To determine: The true statement for the given false statement, “ATP is ideal for the energy currency of the cell because it has most negative standard free energy change of hydrolysis of any phosphorylated compound in the cell”.

Introduction: Adenosine Triphosphate (ATP) is a complex organic system. It provides energy for carrying out various processes in living organisms. It is a driving fuel of the cell. The ATP in the cell is stored as ATP pool. The energy system comprises of high energy phosphates are called the phosphagen system
