Cellular Respiration Stages
|
1. Glycolysis
2. Krebs Cycle (or TCH) 3. Electron Transport Chain (ETC) |
ATP Produced in Cellular Respiration and Glycolysis
|
Glycolysis- 4 but a net gain of 2
|
Energy released from food
|
Gradually released from glucose and other food compounds
|
Electrons carriers in cellular respiration
|
NAD+ and FAD+
|
Types of Fermentation
|
Alcoholic & lactic acid
|
Lactic Acid Process
|
Is a biological process by which glucose, fructose, and sucrose, are converted into cellular energy and the metabolite lactate. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.[1][2][3] If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen.[3] Lactate dehydrogenase catalyzes the interconversion ofpyruvate and lactate with concomitant interconversion of NADH and NAD+.

What enters krebs cycle
|
Pyruvic acid
|
Alcoholic Fermentation
|
P.A+NADH ----> Alcohol + CO2 + NAD+
|
Photo. & Cellular respiration
|
Photo- 6co2 + 6h2o Light> C6H12O6+6O2
c.r.- 6o2+c2h12o6 -----> 6co12 + 6h2o + energy |
