Intro to Energy & Photosynthesis Chapter 8 Ms. Cole

Energy Categories of Organisms. • Autotrophs - get energy from the sun primarily • Examples? • Heterotrophs - get energy from other organisms. • Examples?

ATP • Living organisms use for energy. • Energy comes from the breaking of phosphate bonds.

Section 8 -1 Adenine ATP Ribose 3 Phosphate groups

ADP • Used to store energy. • More stable molecule. • Convert it to ATP when energy is required.

Photosynthesis • The reaction that occurs in chloroplasts of plants. • Produces carbohydrates (sugars) for energy storage and use.

The Equation for Photosynthesis • The reactants and products of the reaction Light energy Carbon dioxide Water Photosynthesis Glucose Oxygen gas Unnumbered Figure 7. 1

Why do leaves change color?

Light rxn Summary Sunlight enters the chloroplast, • adds energy • splits H 2 O • releases O 2 • makes NADPH & ATP for use in dark rxn.

Dark rxn • Calvin Cycle- The 2 nd phase of photosynthesis. • Does not require light. • Uses the NADPH and ATP from the light rxn along with CO 2 to form glucose (C 6 H 12 O 6) • For long term energy storage.
