    Presentation Transcript
    1. Fermentation

    2. Fermentation • Anaerobic: Creates ATP without oxygen • Two Types • 1) Lactic Acid fermentation: ATP created without oxygen • Performed by animals • 2) Alcoholic fermentation • Performed by yeast

    3. Lactic Acid Fermentation • How to relieve sore muscles: • Massage • Bananas • Stretch after • Hydrate • Only performed when muscles are lacking oxygen • During Glycolysis • Glucose broken into fragments to release 2ATP • During Lactic Acid fermentation • Molecules to restart glycolysis created • No ATP made • Lactic acid waste created (causes sore muscles) • The point? Allows muscles to restart glycolysis

    4. Aerobic Respiration Where? In the mitochondria Steps? Kreb’s cycle and electron transport chain What happens? Glucose fragments are converted into 34 ATPs With oxygen present Glycolysis: -- In the cytoplasm -- Glucose is split into 2 ATPs If oxygen is lacking • Lactic Acid fermentation • Where? In the cytoplasm • What happens? • Glucose fragments are broken into lactic acid • Molecules to restart glycolysis created • No ATP created Glycolysis restarts

    5. Alcoholic Fermentation • Performed by microorganisms (yeast) • During Glycolysis • Glucose broken into fragments to release 2ATP • During Alcoholic fermentation • Molecules to restart glycolysis created • No ATP made • Alcohol and CO2 waste created • The point? Allows yeast to restart glycolysis

    6. Kobe Public Service Announcement: Proper Use of Alcohol

    7. The Maple Center Counseling • Safe Rides are available on Friday and Saturday nights from 10:00 pm to 2:00 am for teens living in Beverly Hills. High school students can call for a free ride home when they are under the influence of drugs and/or alcohol. When the teenager calls the Safe Ride number, the TMCC counselor assigned to the 24-hour HELP-LINE arranges for that teen to be picked up by the Beverly Hills Cab Company and taken home. Services are confidential. • (888) 654-3211 for a free ride home.

    8. Kobe Kuiz • Name the two types of fermentation. • How much ATP does glycolysis create? • How much ATP does fermentation create? • Which molecule is needed to start glycolysis? • A buildup of which molecule causes sore muscles? • Which waste molecules are created by alcoholic fermentation?
