(2) Energy And ATP Flashcards
0
Q
Roles of energy
A
(metabolism) Muscle contraction A/T; ions/mols change shape Maintenance/repair/division Prod substances; lysosomes, enzymes & hormones Body temp maint Glycolysis CC mol act; pi, +reactive, AE lowered
1
Q
Energy; (5)
A
Ability to do work Light, heat, sound, electrical etc Change form Not created or destroyed Measured Joules
2
Q
ATP synthase
A
Make
3
Q
ATPase
A
B/D
4
Q
Production of ATP
A
Requires energy
Condensation;
ADP + pi + E -> ATP
5
Q
Conversion of ATP (BD when energy is needed)
A
Releases energy
ATP + H20 -> ADP + Pi + E
6
Q
Photophosphorylation
A
Pi added to ATP ; chlorophyll containing cells
ATP prod during ETC in photosynthesis
7
Q
Oxidative phosphorylation
A
ETC
Mitochondria of plant & animal cells
ATP prod during ETC in respiration
8
Q
Substrate level phosphorylation
A
Plant Animal cells
Pi transferred from donor mol (PYRUVATE)
Glycolysis & Krebs cycle
9
Q
Addition of Pi
A
ADP -> ATP
10
Q
Significance of coenzymes
A
Carry H atoms from one molecule to another
When methylene blue is reduced it becomes blue
11
Q
Coenzymes;
NAD
FAD
NADP
A
NAD : respiration
FAD : Krebs cycle
NADP : photosynthesis
