1. Biology Honors Mrs. Cannavino

2. Write the formula for cellular respiration Label the reactants (inputs) Label the products (outputs) Circle the purpose of this process!! ____ + ____ ____ + ____+ ____

3. Why does life depend on cellular respiration? Cells can’t use glucose as it is, must have ATP to function This includes plant cells! ALL cells must go through cellular respiration

4. The Mitochondrion What’s the function? What do we call this process? CELLULAR RESPIRATION What do we call the energy produced|? ATP What organic molecule needs to be broken down in order to get this energy? GLUCOSE

5. Cristae

6. Anaerobic = NO OXYGEN Glucose is partially broken into lactic acid or ethanol (ethyl alcohol) Small amount of ATP produced Alcoholic fermentation—occurs in plants/bacteria/fungi Lactic acid fermentation—occurs in animals/bacteria –Ex: lactic acid builds up in muscles, causes pH changes—hurts

7. ATP Adenosine triphosphate Molecule that is usable energy for cells Energy is found in bonds between phosphate groups

8. ATP = Life’s Battery ATP is a rechargeable molecule Energy releasing reaction: –ATP loses a P –Adenosine diphosphate is left (ADP) –Energy is released for cellular use Energy storing reaction: –P is reattached to ADP using energy from food –ATP is made again –Energy is stored for next time cell needs it
