Biology Honors Mrs. Cannavino Write the formula for cellular respiration • Label the reactants (inputs) • Label the products (outputs) • Circle the purpose of this process!! • ____ + ____ ____ + ____+ ____ 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 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 Cristae 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 ATP • Adenosine triphosphate • Molecule that is usable energy for cells • Energy is found in bonds between phosphate groups 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
