Respiration Flashcards
What is ATP
Energy rich molecule which releases energy when hydrolysed
Short term energy store
What are the two main forms of phosphorylation
Photosynthetic
Oxidative
What does atp form when hydrolysed and what is the enzyme that catalyses this
ADP + Pi (phosphate)
ATPase
What are some important features of ATP
Immediate energy source
Transported easily
Small amounts
Hydrolysis is single reaction so fine control
Write the chemical equation of respiration
See notes
Draw a flow chart for glycolysis
See notes Glucose ➡️ fructose biphosphate ➡️ triosphosphate ➡️ pyruvate 2ATP in priming stage 1 NAD in each energy conversion 2 ADP + Pi in each energy conversion Nate gain of ATP is 2
Draw a flow chart for the link reaction
See notes
Pyruvate ➡️ Acetate ➡️ Acetyl CoA
NAD in and CO2 out in first part
Coenzyme A in in second bit
Draw the flow chart for the kreb cycle
See notes Citrate (6C) ➡️ oxoglutarate (5) ➡️ oxaloacetate (4) Produces 1 ATP for each Produces 3 NADH for each Produces 1 FADH2 for each
Draw the flow chart for the electron transport chain
See notes
Produces 3 ATP
What happens in oxidative phosphorylation
Protons and e recombine to form H
H links with O to form H2O
Formation of ATP through oxidation of hydrogen
What is the role of oxygen in the electron transport chain
Final acceptor of H atoms
Absense then only glycolysis will take place
What would cyanide do if added to the electron transport chain
Inhibit enzyme cytochrome oxidase
So therefore inhibits respiration
What do lipids produce when hydrolysed
Fatty acids and glycerol
What kind of level of energy do lipids produce
Lots of energy
What do proteins produce when hydrolysed
Amino acids
