2 Biological systems need energy! To do work Chemical activities Growth Movement Reproduction Repair ? Stored in CHEMICAL BONDS

3 Chemical Energy………….. Stored in? Food (Plant or Animal) Made by Producers in? Photosynthesis as? Glucose sugar Energy is released? Respiration, breaks the chemical bonds

4 ATP cell energy Ch.9.1 High energy molecule Supplies cell energy ATP cycles from ADP by addition of a high energy phosphate from the release of chemical energy in respiration

5 ADP to ATP cycle ADP=di phosphate ATP= tri phosphate ATP makes a muscle work ADP in cell ADP +P High energy ATP -P after cell work

6 ADP in cell Stored energy in glucose bonds + Respiration = Release of food energy Forms ATP so cell can do work + P

7 Light energy Ch.9.2 Primary Energy Source for? Photosynthesis Used by Plants Chlorophyll

8 Photosynthesis.... Plants make? Require? 1. Sunlight 2. Chlorophyll 3. Water roots 4. ? gas

9 Plant Photosynthesis…….. Makes Food Uses Sunlight Carbon dioxide Water Chlorophyll

10 Chemical Equation >>>>>> Carbon dioxide + water +energy=food + oxygen (sugar) CO 2 + H 2 0 +sun = C 6 H O 2

11 Cellular Respiration Ch. 9.3 BOTH plants & animals breakdown food 1. Releases energy 2. Makes cell energy 3. Reverse of photosynthesis !

12 Burning versus Respiration Burning: Activated by friction Heat Energy Light Energy Carbon Dioxide Oxygen Respiration: Activated by enzymes Heat Energy ATP cell energy Carbon Dioxide Oxygen

13 Cellular Respiration………. Breakdown of Food Occurs in the Mitochondria of Plant & Animal Cells Produces? ATP cell energy CO 2 gas waste

14 Respiration Equation >>>>> Opposite of Photosynthesis food + oxygen = ATP+ CO 2 +H 2 0 C 6 H O 2 = ATP+ CO 2 +H 2 0

15 Comparison of both …….. PHTOSYNTHESIS Make food Give off O 2 Use sunlight Use CO 2 RESPIRATION Break apart food Use oxygen Make cell energy Give off CO 2

16 Equation Comparison: 6CO 2 + 6H sun = C 6 H O 2 Photosynthesis Respiration C 6 H O 2 = ATP+ 6CO 2 +6H 2 0
