Term
What is cellular resp?
Definition
the process of breaking down glucose (energy stored as ATP)
Term
What are the four parts of the mitochondria used in cellular resp?
Definition
-outer membrane
- inner membrane (cristae)
- matrix
- intermembrane space
Term
Equation for cellular resp
Definition
glucose + 6 oxygen = 6 carbon dioxide + 6 water + energy
Term
calorie
Definition
the amount of heat it takes to heat up 1 gram of water 1 degree celcius
Term
Calorie
Definition
unit for measuring energy in food
Term
convert calorie to Calorie
Definition
1000 calories = 1 Calorie
Term
in cellular resp, what are the carriers of the electrons?
Definition
NAD+ and FAD
Term
equation for NADH
Definition
NAD+ + 2e's + H+ = NADH
Term
Equation for FADH2
Definition
FAD + 2e's + 2H+ = FADH2
Term
what are the three steps of cellular resp?
Definition
1. Glycolysis
2. Kreb's Cycle
3. Electron Transport Chain
Term
Glycolysis = aerobic or anaerobic?
Definition
anaerobic (no oxygen)
Term
Where does the energy to start glycolysis come from?
Definition
ATP
Term
How many ATP's go into glycolysis?
How many come out?
Net gain?
Definition
2 in
4 out
net gain: 2 ATP and 2 NADH
Term
What are the two types of fermentation?
Definition
alcoholic and lactic acid
Term
equation for alcoholic fermentation
Definition
Pyruvic Acid + NADH = Alcohol + carbon dioxide + NAD+
Term
equation for lactic acid fermentation
Definition
Pyruvic acid + NADH = Lactic acid + NAD
Term
Where is alcoholic used?
Definition
in bread and beer and wine
Term
where is lactic aid used?
Definition
in the body after long periods of exercise. (when the body can't supply oxygen to the muscles, lactic acid fermentation occurs. a build up of this lactic acid causes soreness)
also used in cheese, yogurt, ect
Term
what is the point of fermentation?
Definition
fermentation happens so that cells can regenerate the NAD+ needed to keep glycolysis going
