Chapter 11: Energy Metabolism: Respiration
Anaerobic Respiration
Glycolysis and gluconeogenesis reactions run opposite directions
Glucose broken down by Glycolysis
ATP Phosphorylates glucose
Substrate-level phosphorylation
Lactate
Anion of Lactic Acid
Pyruvate
Converted to acetaldehyde
Can be turned back to carbohydrates
Fatty Acids, Ethanol, and also lactic acid
Expensive
Abundant
Toxic Product (Lactate
Acetaldhyde
Abundant
Toxic Product (Ethanol)
Expensive
Oxygen
Somewhat Abundant
Nontoxic product (water)
Cheap
Aerobic Respiration
Water is present
Pyruvate and Acetaldehyde not needed
The Citric Acid Cycle (Krebs Cycle)
Pyruvate goes to cytosol
Electrons are transferred and CO2 ,NADH, and Acetyl CoA is made.
Temperature affects respiration greatly
Electron Transport Chain produces the most ATP out of all the processes of respiration
Respiration In Prokaryotes
Basic Reactions
hydrogen
amino acids
fats
sulfur
sugars
iron
nitrogen
Electron Donors
As well as Hydrogen sulfide and thiosulfate
Hydrogen respiration releases 2 electrons
Oxidized ammonium turns into nitrite
Electron Acceptors
#
Nitrite
Respiring in plants and etc.
potatoes
carrots
lettuce
beans
peaches
wheat
rice
lentils
wine
spirits
