Intro to Chapters Photosynthesis & Cell Respiration

Standards CLE Investigate the relationship between the processes of photosynthesis and cellular respiration. SPI 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: –6CO 2 + 6H LIGHT  C 6 H 12 O 6 + 6O 2 Cellular Respiration Reaction: –C 6 H 12 O 6 + 6O 2  6CO 2 + 6H ATP Products Reactants

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.

Evaluate the interdependence between the processes of photosynthesis and cellular respiration. –CLE Investigate the relationship between the processes of photosynthesis and cellular respiration.
