Cards

Term
ATP
Definition
Adenosine Triphosphate (High energy compound)
Term
Bond attaching phosphate group to adenosine
Definition
Low Energy Bond
Term
Other 2 bonds attaching the phosphate groups
Definition
High energy, unstable, wavy bonds
Term
Energy releasing reaction
Definition
Exergonic reaction
Term
Energy requiring reaction
Definition
Endergonic reaction
Term
Aerobic
Definition
With oxygen
Term
Potential chemical energy of glucose
Definition
Transferred to the bonds of ATP
Term
Glycolysis
Definition
Splitting of glucose, occurs in the cytoplasm, anaerobic (Without oxygen)
Term
Materials needed to begin glycolysis
Definition
2 ATP and hexokinase
Term
Products of glycolysis
Definition
2 Pyruvic Acid and 4 ATP
Term
Net gain of ATP from glycolysis
Definition
2 ATP
Term
Formation of Acetyl Coenzyme A
Definition
Aerobic within mitochondria
2 Pyruvic Acid=2 Acetic Acid and Coenzyme A
Term
Krebs Cycle
Definition
Citric Acid Cycle, series of 8 enzyme mediated steps resulting in the formation of 2 ATP and 4 CO2, requires 6 H20 Molecules, aerobic in mitochondria.
Term
Electron Transport Chain
Definition
During the 1st 3 steps, H+ ions are being "churned" out of the reactions by the action of dehydrogenase enzymes.
Term
ETC and Chemiosmosis
Definition
Oxidative Phosphorylation
Term
NAD and FAD
Definition
2 Coenzymes that accept and transfer H ions forming NADH and FADH.
Term
NADH and FADH
Definition
Give up their electron to the electron transport chain found within the cristae supplying electron energy to push protons into the intermembrane space. (creating proton gradient)
Term
Chemiosmosis
Definition
The potential energy of the proton concentration gradient is harnessed by the ATP synthase to endergonically combine 32 ADP and 32 P into 32ATP.
Term
Waste Product Water formation
Definition
Combination of H ions and oxygen
Term
Other Energy sources besides glucose
Definition
Lipids and Protein
Term
Lipids are broken down into
Definition
Fatty acids and glycerol
Term
Proteins are broken down into
Definition
Amino Acids
Term
Diagram showing the meeting of all energy sources
Definition
Crossroads Compound
Term
Anaerobic Respiration
Definition
Many microbes respirate without oxygen, also within humans deprived of oxygen.
Term
2 Forms of Anaerobic Respiration
Definition
Alcoholic Fermentation and Lactic Acid Fermentation
Term
Alcoholic Fermentation
Definition
2 Pyruvic Acid to 2 Ethyl Alcohol(ethanol) and CO2.
Term
Anaerobes
Definition
Cannot utilize NADH, so the H ions will be donated back to forming pyruvic acid and will regenerate NAD.
Term
Lactic Acid Fermentation
Definition
2 Pyruvic Acid to 2 Lactic Acid, NAD regenerated.
Term
5 Examples of Helpful Fermentation
Definition
Distilling Alcohol, Bread Making, Vinegar, Dairy Industry, Sauerkraut.
Term
2 Examples of Harmful Fermentation
Definition
Food Spoilage, Muscle Fatigue
Term
Result of food spoilage
Definition
Bacteria release poisons, food poisoning
Term
Result of muscle fatigue
Definition
Lactic acid build up during strenuous activity (Cramps)
Term
Time it takes to start burning reserved calories
Definition
20 Minutes or More
Term
Glycogen
Definition
Animal Starch
