1What is Cellular Respiration?
Breaking down glucose to create energy from ATP
2What is the Essential Purpose of Cellular Respiration?
To make ATP from ADP and inorganic phosphate (Pi)
To make energy bitch
3What is the net reaction of Cellular Respiration?
C6H12O6 + 6O2 --> 6H2O + 6CO2 + 36 ATP
4Where is chemical energy stored?
In the bonds of molecules. As bonds break, energy is released.
5What is ATP used for?
-Basic energy currency of the cell
-Used to transfer energy
-Provides energy for protein syntheses and muscle contraction
6Aerobic Respiration
-Occurs in the precense of O2
-Begins in the cytoplasm and ends in the Mitochondria
7Anaerobic Respiration
-Occurs without O2
-Stays in the cytoplasm and only produces 2 ATP
8What is ATP made of?
5 carbon sugar
Nitrogen base
3 phosphate molecules
AMP -> ADP -> ATP
9Mitochondria
-Powerhouse of the cell, produces large quantities of ATP
-Outer membrane and Inner Membrane
Contain their own DNA (MTDNA) and can reproduce itself
10Glycoloysis
-Stage 1 of both Aerobic & Anaerobic Respiration
-Is a series of 10 chemical reactions
-Breaks glucose into two small molecules called pyruvate
-Does not require oxygen
-2 NAD react with hydrogen ions and become NADH
-Energy builds up and releases as 4 ATP (including net gain)
-Occurs in the cytoplasm
11Pyruvate Oxidation
-Stage 2
-Occurs in the Matrix
1. A CO2 molecule is removed from each pyruvate and released as a waste product.
2. Carbon portions are oxidized and become NADH
3. Coenzyme A forms Acetyl-CoA
12Krebs Cycle
-Stage 3
Each acetyl CoA produces
-2 CO2 Molecules
-3 NADH
-1 FADH2
-1 ATP
NADH and FADH2 enter stage four, while CO2 is excreted
13Electron Transport
-Stage 4
-NADH and FADH2 transfer electrons
-Oxygen is vital
-Large emounts of energy are released and used to pump H+ ions across the intermembrane space
-Flow through ATP Synthase to product ATP
-32 ATP molecules are produced in Stage 4
14Alcohol Fermentation
-In yeast and other organisms, anaerobic resp produces ALCOHOL and CO2
-Pyruvate is converted
-NADH reduces the converted Pyruvate into Alcohol
-Recycles NAD+ which helps continue glycolysis
15Lactic Acid Fermentation
-During hard excersize, muscles demand more energy
-In animal cells, glucose is broken down producting Lactic Acid and 2 ATP w/o O2
-Recycles NAD+
-Lactic acid causes the burning sensation, stiffness, and fatigue in muscles after excersize
16Lactic Acid Threshold
How much exertion can your body handle until lactic acid production spikes.
