Q

how is atp formed ( phosphorylation )

A

atp is formed by phosphorylation when the ENZYME atp synthase combines ADP and Pi (inorganic phosphate) in a condensation reaction

Q

how is atp hydrolysed and into what

A

by enzyme ATPase - it hydrolyses the terminal phosphate bond - releasing pocket of 30.6kj energy

makes ADP and Pi

Q

advantages of getting energy from atp instead of directly from glucose

Study These Flashcards
A
  • immediate energy where and when its needed
  • only one enxyme to release energy from atp - many needed to release energy from glucose
  • atp easily transported across membranes
  • atp is universal currency
24
Q

where does glycolysis happen

Study These Flashcards
A

cell cytoplasm

25
where does link reaction happen
mitochondrial matrix
26
where does the Krebs cycle happen
mitochondrial matrix
27
where is electron transport chain
inner mitochondrial MEMBRANE - cristae
28
catabolic meaning
molecules broken down releasing energy
29
anabolic meaning
molecules build up taking energy in
30
whats oxidation
loss of electrons / hydrogen
31
whats reduction
gain of electrons / hydrogen
32
name the 2 co enzymes that act as hydrogen carriers \9 means get reduced)
reduced NAD reduced FAD
33
how does glucose enter the cell cytoplasm
facilitated diffusion through instrinsic carrier protein
34
describe glycolysis
start w/ glucose - 2ATP gives 2Pi and leaves becoming 2ADP This forms hexose phosphate this then splits into 2x triose phosphate One hydrogen removed from each triose phosphate by dehydrogenase NAD comes to pick this hydrogen becoming reduced NAD 2ADP combine w/ Pi to make ATP on each side so 4 ATP made this makes pyruvate on each side
35
Net ATp in glycolysis
2
36
what type of phosphorylation happens in glycolysis
substrate-level phosphorylation
37
does glycolysis only happen in aerobic
no - both
38
how many times does the link reaction take place per glucose molecule
2x
39
role of nad and fad
h carriers to etc
40
which product from glycolysis enters the link reaction
pyruvate
41
describe + diagram of link reaction
pyruvate enters the mitochondria by facilitated diffusion is then decarboxylated by decarboxylase enz - which removes one molecule of co2 and also dehydrogenated by dehydrogenase - the removed H collected by NAD to become reduced NAD this results in acetate formed acetate combines with coenzyme A - which transports acetate to the Krebs cycle the acetate + coenzyme A complex is called acetyl coenzyme A
42
is any atp made in link reaction?
no
43
what are the products of link reaction per glucose molecule?
link reaction per glucose - x2 therefore Reduced NAD per glucose = 2 CO2 per glucose = 2 acetylecoenzymeA per glucse mol - 2
44
how many pyruvates per glucose molecule
2
45
why is it adv to have pyruvate as intermediate why we need to convert and don't just keep glucose
cos YES - carrier protein to in mitochondria to transport pyruvate in it NO - carrier protein to carry glucose molecule from cyto to mito
46
role of acetylecoenzymeA
Transports acetate from link to krebs cycle
47
how many times does krebs cycle happen pgm
acetylecoenzymeA ---> 6C ----> 5C ----> 4C -----> 4C
48
IN KREBS PGM HOW WHAT AND HOW MANY PRODUCTS FORMED (what type of atp formed)
PGM redNAD - 6 co2 - 4 redFAD -2 ATP - 2 --- subs level phoshorylation
49
decarboxylation meaning
chemical reaction in which a carboxyl cooh group removed catalysed by carboxylase enzyme
50
dehydrogenation meaning
chemical reaction where hydrogen removed by dehydrogenase enzymes
51
where does the etc take place
inner mitochondrial membrane
52
which particles in mito make atp and what are they called
at synthase aka stalked particles found on the inner mito membrane
53
why is it an adv for the inner mito membrane to be folded into cristae
increased sa - so more atpp synthase - so more atp made
54
2 functions of the mito dna
self relication codes for many enzymes involved in aerobic resp
55
by what process is atp formed in the etc and which type of phosphorylation
oxidative phosphorylation by chemiosmosis
