What is energy in biology? ATP Adenosine TriPhosphate Whoa!HOT stuff!
What is energy? Calorie = Energy A calorie is a heat unit of energy
How do we define Cellular Respiration? Release energy from food to make ATP
Who does Respiration? All Living Organisms!
Aerobic Resp Anaerobic Resp. Req. OXYGEN NO OXYGEN Makes a LITTLE ATP Makes a LOT ATP
Aerobic or Anaerobic? BACTERIA PROTIST FUNGUS (YEAST) PLANTS ANIMALS
ANAEROBIC 1st Step: Glycolysis – Splitting of Glucose EXERGONIC (energy releasing) Phosphorylation NAD
Where does glycolysis occur? CYTOPLASM
FERMENTATION Respiration with NO oxygen
Chapter 23 Bacteria and Yeast in Food Production
What happens to the pyruvate? FERMENTATION: yeast & bacteria
Fermentation in Humans Lack of Oxygen Build up of Lactic Acid in Muscles
AEROBIC RESPIRATION Where does it occur in a cell?
Why the extra layers? Increase Surface Area MITOCHONDRIA
AEROBIC RESPIRATION If O2 is present! Pyruvate STEP 1: Glycolysis Pyruvate Glucose STEP 2: Kreb Cycle STEP 3: Electron Transport Chain (ETC)
ATP released for cellular work CO2 + H2O Glucose many tiny steps
CHLOROPLAST Increase Surface Area
CHLOROPHYLL • green pigment • converts solar energy into chemical energy (ATP)
