Presentation (Introducing the

lesson which is the Glycolysis, the first

stage of cellular respiration).

Motivation (Rap Video clip about

glycolysis)

Discussion

• Cellular Respiration

-Is a complex process by which food molecules are broken down to release energy in the form of ATP. -It is a stage that begins with Glycolysis.

Glycolysis -the first stage of the aerobic cell respiration, a process in which glucose is degraded to form two pyruvic acid molecules along with the formation of 2 ATP and 2 NADH. -this process does not require oxygen and not yield much energy.

Function of Glycolysis

to form NADH and ATP as a source of energy to cells.

to produce pyruvate used in the citric acid cycle.

Glyco – GlucoseLysis - breakingGoal : breaking glucose

down to form two pyruvates.

Who : all life on earth performs Glycolysis.

Where : Cytoplasm

2 Phases :1. Energy Investment

Phase -stage where there is a consumption of ATP. - phosphorylation of Glucose and its conversion to glyceraldehyde-3-phosphate.

2. Pay Off Phase - oxidative conversion of glyceraldehyde-3-phosphate to pyruvate and converted formation of ATP and NADH. - there is the production of ATP.

Raw material of Glycolysis: Glucose

By product :2 ATP2 NADH2 PYRUVATE

Let the student demonstrate the process of glycolysis

Evaluation

1-3. What are the by product of glycolysis?2. It is a raw material of Glycolysis?3. Where specific organelle does glycolysis occur?

Answer key

1. 2 ATP2. 2 NADH3. 2 PYRUVATE4. Glucose5. Cytoplasm
