Biological systems need energy! To do work Chemical activities Growth Movement Reproduction Repair ? Stored in CHEMICAL BONDS
Chemical Energy………….. Stored in? Food (Plant or Animal) Made by Producers in? Photosynthesis as? Glucose sugar Energy is released? Respiration, breaks the chemical bonds
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
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
ADP in cell Stored energy in glucose bonds + Respiration = Release of food energy Forms ATP so cell can do work + P
Light energy Ch.9.2 Primary Energy Source for? Photosynthesis Used by Plants Chlorophyll
Photosynthesis.... Plants make? Require? 1. Sunlight 2. Chlorophyll 3. Water roots 4. ? gas
Plant Photosynthesis…….. Makes Food Uses Sunlight Carbon dioxide Water Chlorophyll
Chemical Equation >>>>>> Carbon dioxide + water +energy=food + oxygen (sugar) CO 2 + H 2 0 +sun = C 6 H O 2
Cellular Respiration Ch. 9.3 BOTH plants & animals breakdown food 1. Releases energy 2. Makes cell energy 3. Reverse of photosynthesis !
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
Cellular Respiration………. Breakdown of Food Occurs in the Mitochondria of Plant & Animal Cells Produces? ATP cell energy CO 2 gas waste
Respiration Equation >>>>> Opposite of Photosynthesis food + oxygen = ATP+ CO 2 +H 2 0 C 6 H O 2 = ATP+ CO 2 +H 2 0
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
Equation Comparison: 6CO 2 + 6H sun = C 6 H O 2 Photosynthesis Respiration C 6 H O 2 = ATP+ 6CO 2 +6H 2 0
Photosynthesis Photosynthesis- A process by which plants convert sunlight, water, and carbon dioxide into food energy (sugar), oxygen and water.
Photosynthesis Section: 2.3. The sun provides almost all the energy used by living things on Earth.
