Bio Ch 9 Flashcards
Glucose is an example of a
High energy molecule
Why is ATP constantly being made
It has such high PE so it is unstable and isn’t stored
Example of a storage carbohydrate
Starches and glycogen
what happens when glucose is oxidized
The PE stored is converted into kinetic energy forms of heat and light
Difference between cellular respiration and fermentation
Cellular respiration “burning” harvests more energy from glucose since it is the complete oxidation of carbons in glucose to coz. Fermentation doesn’t fully oxidize glucose, it produces waste
Four steps of cellular respiration
Glycolysis
Pyruvate processing
Citric acid cycle
Electron transport and oxidative phosphorylation
What happens in glycolysis
6 Carbon glucose is broker down into pyruvate
ATP is made from ADP
NAD+ is made into NADH
What happens in pyruvate processing
The pyruvates made from glycolysis are processed to release CO 2 and acetal coa
What happens in the citric acid cycle
The carbons in acetal coa are oxidized to Co 2
ATP and NADH is produced
Fad is reduced to FADH 2
What happens in electron transport and oxidative phosphorylation
NADH und FADH 2 electrons move through electron carriers (etc).
The energy here is used to create a proton gradient across a membrane which makes sure protons form ATP
What is oxidative phosphorylation?
Oxidation reactions are used for a proton gradient to form ATP
Cellular respiration is
Set of reactions that use electrons from I energy molecules to produce ATP via electron transport chain
Acetal COA is the starting point for
Anabolic pathways that make fatty acids
Substrate level phosphorylation
Production of ATP by the transfer of phosphate group
Phosphofrucktokinase
Enzyme that synthesizes fructose 1,6 bisphosphate from fructose 6p phosphate
