Explanation / Answer

Glycolysis:- Glycolysis is a catabolic process where 1 molecule of glucose , a 6-C sugar is broken down into 2 X 3-C molecules of Pyruvate . This operates within the cell only in an area called the Cytoplasm. Glycolysis can operate with or without Oxygen.

Fig.3.13 shows glycolytic pathway which converts 1 glucose into 2 pyruvate in a 9-step enzymatically controlled process. Besides the 2-Pyruvate being made, the energy releasing step of glycolysis includes 2 NADH carrier molecules and 4 ATP molecules per glucose.

What is the net gain of ATPs per glucose? 2 ATP.

Lactic acid pathway:- Also known as fermentation or the breakdown of glucose in the absence of Oxygen .

Fig.3.22. NADH gives its H+ to pyruvate which forms lactate.

Lactic acid formed by working skeletal muscles can be recycled. It will get carried off by the blood stream to the Liver where lactate gets converted into glycogen.

Aerobic respiration:- Cellular respiration occurs in 3 major stages locate within the cell ( Glycolysis takes place in the cytoplasm, Kreb's cycle takes place in the mitochondrial matrix, and electron transport system takes place in the inner mitochondrial membrane.

Aerobic respiration begins with Pyruvate formed by glycolysis enters the mitochondria and we will follow the complete oxidation of pyruvate through kreb's cycle.

Fig. 3.15 & 3.16 Aerobic cellular respiration requires oxygen and glucose or fatty acid which get completely oxidized (or broken down = catabolized) into CO2 and water yielding 2 molecules of ATP.

1st stage:- Organic fuel molecules (glucose , fatty acid , certain amino acids ) are oxidized to yield 2-C fragments in the form of the acetyl group or acyl coenzyme-A , (A-coA).

2nd stage:- These acyl groups are fed into Kreb's cycle , which enzymatically oxidizes them to CO2, the energy released by this oxidation process is conserved in the reduced electron carriers NADH and FADH2.

3rd stage:- During cellular respiration, these reduced cofactors will become oxidized therefore , giving up protons (H+) and electron(e-) , The e- get transferred along a chain of e- carrying molecules known as electron carriers by electron transport system to oxygen, which they reduce to form H2O.

During this process of e- transfer, much of the energy released and conserved in the form of ATP.

The production of ATP through the coupling of the electron transport system with phosphorylation of ADP is termed Oxidative phosphorylation.

During fat and protein metabolism (lipolysis and Amino acid metabolism ) energy derived from cellular respiration of lipids and proteins using the same aerobic pathways found in Kreb's cycle and the metabolism of Acyl co-A.

Explanation:- Glycolysis is a catabolic process , as it is the 1 st step where breakdown of glucose takes place to release energy for cellular metabolism. Glycolysis can takes place both in presence and absence of oxygen in cytoplasm of cell. In case of aerobic respiration glycolysis leads to Kreb's cycle, and in case of anaerobic respiration it leads to fermentation.

Glycolysis contains an energy releasing phase and an energy utilising phase, the net gain of ATP is 2 in glycolysis. Gluconeogenesis is the process where lactate gets converted to glycogen by kori cycle in liver and it can be reutilised for energy.

Cellular respiration has three phases glycolysis taking place in cytoplasm and kreb's cycle takes place in mitochondrial matrix and ETS which takes place in inner mitochondrial membrane.

Glycolysis produces 2 molecules of ATP, 2 NADH which are electron carriers, and 2 pyruvate. Pyruvate enters the mitochondria by pyruvate-translocase, here it is converted to acetyl Co-A to get used in kreb's cycle, Kreb's cycle is the aerobic respiration phase it produces 6 NADH, 2 ATP, 2 FADH2, NADH and FADH are electron carriers.

Electron transport system and phosphorylation of ADP cobinedly called Oxidative phosphorylation.

kreb's cycle is related with fat and protein metabolism.
