Photosynthesis

What is Photosynthesis? Process of converting sunlight with Carbon Dioxide and Water to create Glucose (SUGAR) and Oxygen

Balanced Equation 6 Carbon Dioxide molecules + 6 Water molecules yields 1 Glucose molecule and 7 Oxygen molecules

Oxygen is released The H is added to NADP to make NADPH. The ATP and NADPH move on to the next step – the Calvin Cycle

Light independent – does not require light The ATP and NADPH from light reactions have energy that is used to convert CO 2 into sugar Once the ATP and NADPH have given up their energy they are recycled back as ADP and NADP.

If Oxygen is released from P.S. what happens next? CELLULAR RESPIRATION!

Anaerobic Respiration When oxygen is present, glycolysis leads to other pathways which release a great deal of energy. If oxygen is not present, glycolysis is followed by a different pathway called fermentation.

Alcoholic Fermentation Yeasts form ethyl alcohol and CO 2 as waste products. Unleavened bread = pita Leavened bread = sandwich bread Pyruvic acid + NADH  alcohol + CO 2 + NAD +

Lactic Acid Fermentation Lactic acid is produced instead of alcohol. Lactic acid is produced in your muscles during rapid exercise when the body cannot supply enough oxygen to the tissues. Muscles will produce ATP from lactic acid fermentation causing a painful, burning sensation in your muscles. Cheese, yogurt, buttermilk and sour cream are formed from prokaryotes and lactic acid fermentation.
