Step 3 The Electron Transport Chain

What is the FINAL ELECTRON ACCEPTOR?

The FINAL ELECTRON ACCEPTOR is (o2)

What makes the ATP? ATP synthase creates (ATP).

Where do the hydrogen ions build up after they are stripped from NADH and FADH2? Hydrogen ions build up from the Inter membrane space

Picture of (ETC)

ATP by ATP synthase NAD+ FAD+2

NADH FADH2

Where "Electron Transport Chain" takes place?(ETC) happens inside the cristae of mitochondria;

Unit 4 Respiration

Topic 4.2 Anaerobic Respiration

glycosis

breaks down glucose by enzymes, releacing energy and pryuvic acid

outputs

2 pryuvates 2 NADH 2 ADP 4 ATP 2 ATP

inputs

glucose 2 NAD+ 2 ATP 4 ADP+ 4P

Topic 4.1 Enzymes

Need to know: Benefits are it's "Speed" & produce co2 In Anaerobic Respiration; Plant makes "Alcoholic Fermentation" & Animals makes "Lactic Fermentation" {2 ATP's produced anaerobic respiration} Competitive inhibitor & NON - competitive inhibitor (CI) - mimics substrate and competes (NCI) - does not mimic substrate or competes

Define: Enzyme-Proteins substrate is the thing the enzymes goes after. activation energy-the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction anabolism- In your body where it is (Building up) catabolism-Breaking down Should Do's Descrbe how enzymes help chemical reactions in the body. enzymes can be regulated. 1. comparmentalization 2. substrate availability 3. enzyme quantity proteases-partially break down protein in baby food to make it easier to digest lipases-breaks fats down into fatty acids and glycerol amylase-a carbohydrate - an enzyme that breaks down starch into glucose

Photosynthesis Vs Respiration

Photosynthesis:only occurs in plants and some bacteria Products Glucose & Water Reactants: Carbon dioxide & Water Located in the "Chloroplast" "Stores" Energy 6Co2+6H2o+light > 6o2+c6H12o6

Respiration: Involved in all living things Products Carbon & Water Reactants: Glucose & Oxygen Located in "Mitochondria" Energy "Releases 6o2+C6H12o6 > 6Co2+6H2o+Energy

Mitochondria Vs Chloroplast

Topic 4.0 Respiration

what about the ETC???

What about anaerobic respiration and enzymes

Step 2 Krebs cycle

need to know: define what is krebs cycle and what happens during krebs cycle

Summary - the krebs cycle is a cycle that breaks pyuvate down into carbon dioxide Where? occurs in the matrix of the mitochondria

8 NADH 2 CO2 2 ATP 2 CoA 2 FADH2 4 CO2

Inputs

2 pyruvate 8 NAD+ 2 ADP 2 FAD

STEP 1 Glycolysis

Need To Know: Define "Glycolysis"

1. The breakdown of glucose by enzymes, releasing energy and pyruvate acid.

Subtopic

Outputs

Two Pyruvate, 2 NADH 4 ATP

Input

1 Glucose 2 NAD+ 2ATP
