Respiration Flashcards
(22 cards)
Advantage of ATP as energy source
Energy is available for immediate use
Nitrogenous base and sugar in ATP
Nitrogenous base-adenine
Sugar-ribose
Aerobic respiration
C6H12O6+6O2————>6CO2+6H2O+energy
Glucose storage polysaccharide and location
Glycogen
Location:liver
3 products of the Krebs cycle
- NADH
- ATP
- CO2
Final electron acceptor in aerobic respiration
Oxygen
3-carbon molecule
Pyruvic acid
Pathway where pyruvic acid is produced
Glycolysis
Pyruvate
-Converted to Acetyl CoA in stage 2 where it loses co2 molecule
-Krebs cycle:energy released from Acetyl CoA in form of high energy electrons which combine with NAD+ to for NADH
Electron transport system:low energy electrons combine with oxygen and hydrogen to form H2O
Fate of pyruvate when no oxygen is available
Muscle-lactic acid
Yeast-ethanol and co2
Stage 1 and location
Glycolysis and cytosol
Stage 2 and location
Krebs cycle and lumen of mitochondria
Stage 3 and location
Electron transport chain and cristae
Function of water
Transport
Medium for all chemical reactions
2 processes which require ATP
Respiration
Photosynthesis
Krebs cycle
2nd stage of aerobic respiration
Acetyl CoA broken down to co2 and protons
Releases high energy electrons which combine with NAD+ to form NADP
ADP
Adenosine di-phosphate
Low energy molecule
Combines with a phosphate and energy molecule to form ATP and water
Glycolysis
1st stage of respiration
Takes place in cytosol
Anaerobic process
Low-energy release
Role of NAD/NADP+
Transferring electrons
Role of electrons
Used in making of H2O
Production of alcohol by yeast
Add yeast and glucose to conical flask
Add glucose to separate flask(control)
Attack fermentation lock to both
Leave in incubator at 30 degrees overnight
To show presence of alcohol
Add potassium iodide and sodium hydrochloride
Put in a water bath for 4-5 mins
Allow to cool
Presence of alcohol will result in yellow crystals
