Q

ENERGY SOURCE

A

FOOD=ATP

21
Q

Is the unit amount for the amount of energy needed to raise the temp of 1 gm of water 1 degree celsius

A

Calorie

22
Q

1 calorie gets you approximately

A

9000 ATP’s

23
Q

Food you will eat will be used for restoring ___ lost as heat, waste or stored for later use.

A

ATP

24
Q

If oxygen presents, it will lead to two other pathways that release a lot of energy

A

Krebs Cycle and Electron Transport Chain

25
Q

1st pathway, and releases only a small amount of energy (2 net ATP)

A

Glycolysis

26
Q

If oxygen absent, glycolysis is followed by a different pathways;

A

Alcoholic Fermentation, Lactic Acid Fermentation

27
Q

Where is this ATP produced in a Cell

A

Mitochondria

28
Q

Double membrane bound organelle.

A

Mitochondria

29
Q

Inner membrame of Mitochondria encloses a fluid filled;

A

Matrix

30
Q

Folded project into the matrix

A

Cristae (Increases surface area)

31
Q

Small Circular DMA

A

Mitochondria

32
Q

Glucose + Oxygen ——— Carbin Dioxide +Water + ATP!

A

Cellular Respiration

33
Q

Two ways to break down food

A

Anaerobic cellular respiration; also called fermentation
Aerobic cellular respiration; commonly called cellular respiration

34
Q

In the presence of oxygen (aerobic) glycolysis is followed by;

A

Krebs Cycle & Electron Transport Chain

35
Q

All three combined make up Cellular Respiration; Process that releases energy by breaking down food molecules in the presence of oxygen

A

Glycolysis+ Krebs Cycle +Electron Transport Chain

36
Q

Equation for Cellular Respiration

A

6O2+ C6H12O6 ——- 6CO2 + 6H20 + energy (ATP)
oxygen + glucose —— carbon dioxide + water + energy

37
Q

3 stages that captures some of the chemical energy available in food molecules and uses it to produce ATP

A

Glycolysis, Krebs Cycle, Electron Transport Chain and Oxidative Phosphorylation

38
Q

Occurs in the cytoplasm of cell. Anaerobic process (No oxygen). Glucose is broken down into 2 molecules of Pyruvic Acid. NADH is produces and carries the high energy electrons to the ETC (last step). Total ATP made are: 2

A

Glycolysis

39
Q

Process takes place into cytosol of the cytoplasm outside the Mitochondria; converts glucose with the help of 2 ATO molecules and eventually releases 4 ATP molecules for a net gain of 2 ATP molecules.

A

Glycolysis

40
Q

Yields a net of 2 ATP

A

Glycolysis

41
Q

The fluid around the organelles (Suspended molecules of sugars and etc.)

A

Cytosol

42
Q

The cytosol PLUS the organelles suspended within it (everything except NUCLEUS)

A

Cytoplasm

43
Q

It does not require oxygen and it can supply chemical energy to cells when oxygen is NOT available

A

Glycolysis

44
Q

If a cell generates large amount of ATP from glycolysis

A

Became filled up with electrons, Cannot proceed without NAD+ molecules and ATP PRODUCTION STOPS

45
Q

Location is Mitochondria. Process cells use to get the most energy out of food molecules, Aerobic (With Oxygen) and has two processes:

A

Aerobic Respiration

46
Q

Two processes of Aerobic Respiration

A

Krebs Cycle and Electron Transport chain

47
Q

Extracted by world’s most powerful electron receptor

A

Oxygen (Aerobic Respiration)

48
Q

Krebs and Electron Transport require oxygen thus they are;

A

Aerobic processes

49
Q

Location is matrix of Mitochondria.
Pyruvic acid is broken down into Acetyl Co-enzyme A. C02 is produced. Electron Carriers produced FACH2 and NADH.
NET OF 2 ATP ARE FORMED (1 from each pyruvic from glyco)

A

Krebs Cycle
