Glycolysis Review

Glycolysis and Respiration 2 O No 2 O fer me nt ati on glycolysis • Glycolysis – Creates: ATP, Pyruvate, NADH – Leads to either: 1) Aerobic Respiration § With oxygen present § Kreb’s (Citric Acid) Cycle § Electron transport chain 2) Anaerobic Respiration § Without oxygen § Fermentation

Lactic Acid Fermentation During heavy exercise, the oxygen you inhale mainly goes to your brain. Your muscles are now lacking oxygen. There But your must muscles be a way need to ATP if. ATP make you want without to the continue help of oxygen. your exercise. • Glycolysis – Glucose (6 C) broken down into two pyruvates (3 C) – 4 ATP + NADH created • L. A. F. Step 1: Happens when muscles do not receive oxygen – NADH breaks down pyruvates into lactic acid (causes burn) – Lactic acid breaks down upon oxygen returning • L. A. F Step 2: NAD returns to glycolysis • Glycolysis can break down another glucose to create 4 ATP

How to relieve sore muscles: 1)Massage 2)Bananas 3)Post stretch 4)Hydrate

Alcoholic Fermentation CO 2 from yeast causes bread to rise. So why is bread nonalcoholic? • Glycolysis – Glucose (6 C) broken down into two pyruvates (3 C) – 4 ATP + NADH created • A. F. Step 1: Happens in yeasts & some plants – NADH breaks down pyruvates into ethanol and CO 2 • A. F. Step 2: NAD returns to glycolysis • Glycolysis can break down another glucose to create 4 ATP

Recap • What does the word aerobic imply? Anaerobic? • How many ATP molecules are created by either type of fermentation? • Before fermentation, which process must first take place? • What is produced during glycolysis? • Which molecule from glycolysis is used to break apart pyruvate during fermentation? • Besides alcohol, what is a waste product of alcoholic fermentation? • Where can you find the phone number to the Maple Counseling Center and Safe Ride?
