Review Photosynthesis

Respiration

?Why do you breathe? To release energy! Just like a fire needs oxygen to burn, our cells need oxygen to “burn” the sugar in our cells To release energy!

Cellular Respiration The process where cells obtain glucose from food and break it down to release energy Energy! The opposite of photosynthesis

Reactants Products Glucose Carbon Dioxide Water Oxygen Energy (ATP)

6CO2 + 6H20 C6H1206 + 6O2 Respiration Equation Reactants Products Energy! C6H1206 + 6O2 6CO2 + 6H20 + Energy (ATP) Notice anything? It’s the flip of photosynthesis….. 6CO2 + 6H20 C6H1206 + 6O2 Sunlight (energy)

Powerhouse? Aerobic Respiration takes place in the mitochondria Similar to the chloroplast the Mitochondria has membranes that are folded to allow for more surface area for chemical reactions. Anaerobic Respiration takes place in the cell’s cytoplasm

This is the cells way of storing and using energy ATP ATP- Adenosine Triphosphate ADP- Adenosine Diphosphate It’s a Nucleotide Phosphate Sugar Base

ADP ATP

ATP/ADP cycle ENERGY! All of the energy is stored between the 2nd and the 3rd phosphate of ATP

ATP/ADP cycle To release energy break off the 3rd phosphate To store energy add a 3rd phosphate

ATP/ADP cycle

ATP/ADP cycle ATP= ADP= Used battery Recharged battery

ATP/ADP cycle ATP= ADP= Used battery Recharged battery

Who does respiration? When does it happen? All the time Every living thing When does it happen? All the time

There are two types of Respiration Aerobic With oxygen This make a lot of energy Feel the Energy!!! YEAAA! 36 ATP

Makes your muscles sore! No oxygen Anaerobic Respiration I’m so tired! Also called Fermentation Only Makes 2 ATP Alcohol Fermentation Yeast Ouch! Makes your muscles sore! Lactic Acid Fermentation Bacteria and Muscles

Which organisms do this? Respiration Photosynthesis Reactants Products Which organisms do this? Where in the cell does this happen? Carbon Dioxide Water Light Glucose Oxygen Carbon Dioxide Water Energy (ATP) Glucose Oxygen Producers (Plants) Every living thing Chloroplast Mitochondria or Cytoplasm
