Notes 2.5: Photosynthesis and Cellular Respiration These are guided notes: fill in blanks on your worksheet

Objectives I can explain how photosynthesis and cellular respiration are related. I can identify where photosynthesis and cellular respiration occur in the cell. I can recite the reactants and products of photosynthesis and cellular respiration.

Photosynthesis & Cellular Respiration

Review: Forms of Carbon In the atmosphere (sky) carbon is carbon dioxide In the bodies of plants and animals, carbon is sugar Carbon can change forms by 2 processes: photosynthesis and cellular respiration

Review: Chemical Reactions Reactants = before the arrow Products = after the arrow

What is Photosynthesis? Photo= Light Synthesis= To make or put things together

Photosynthesis Photosynthesis: how plants make sugar (glucose) from sunlight and CO2 carbon dioxide glucose

Photosynthesis Plants make (products): glucose, oxygen (O2) Plants use (reactants): CO2, water (H2O), sunlight 6CO2 +6H2O +sunlight C6H12O6 + 6O2 Photosynthesis:

Photosynthesis Photosynthesis is done by plants only Organelle for photosynthesis = chloroplast!

What is the equation?

Photosynthesis Photosynthesis: 6CO2 +6H2O +sunlight C6H12O6 + 6O2

Photosynthesis Rap

So what happens when you breathe? BUT IT’S NOT THIS SIMPLE…. Oxygen (O2) goes in Carbon dioxide (CO2) goes out

Respiration C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP Respiration: how all organisms change sugar to CO2 and usable energy (ATP) People doing respiration make: CO2, water (H2O), ATP People doing respiration use: sugar, oxygen C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP

Respiration C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP

Respiration Respiration is done by animals and plants Organelle for respiration = mitochondria!

What is the equation?

Photosynthesis 6CO2 +6H2O +sunlight C6H12O6 + 6O2 Photosynthesis:

Respiration C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP

The process that makes sugar

The process that makes ATP

The process that makes energy

Performed in the mitochondria

Performed in the chloroplast
