Intro to Chapters 6 - 7

Photosynthesis &

Cell Respiration

Standards

• CLE 3210.3.3 Investigate the relationship between the processes of photosynthesis and cellular respiration.

• SPI 3210.3.3 Compare and contrast photosynthesis and cellular respiration in terms of energy transformation.

Objectives (Today, I will…)

• Compare and contrast photosynthesis and cellular respiration in terms of energy transformation.

• Evaluate the interdependence between the processes of photosynthesis and cellular respiration.

Biochemical Pathways

• Definition:

• Two biochemical pathways we will study:

• Clip from book.

The long chains of chemical reactions that take place in the normal operation of living systems.

Photosynthesis & Cellular Respiration

The Big Picture

Photosynthesis

Cellular Respiration

Interdependence

• Photosynthesis Reaction:– 6CO2 + 6H20 + LIGHT C6H12O6 + 6O2

• Cellular Respiration Reaction:– C6H12O6 + 6O2 6CO2 + 6H20 + ATP

Overview of Photosynthesis

• Two Stages:– Light Cycle:

– Calvin Cycle:

Takes sunlight & water to make ATP & NADPH

Takes the ATP & NADPH from light cycle to make sugar, starch, and amino acids.

Overview of Cell Respiration

• Two Stages:– Glycolysis

– Aerobic Respiration

Takes glucose to make pyruvic acid and some ATP

Takes pyruvic acid and oxygen to make ATP for the cell.
