respiration Flashcards
What is glycolysis? (4 marker) make 4 points💓
-phosphorylation of glucose using ATP
-oxidation of triose phosphate to pyruvate
-NAD is reduced
-net gain of ATP
what are the 2 types of anaerobic respiration and which is animal and plant 🩷
ethanol fermentation (plant) and lactate fermentation (animal)
what’s ethanol fermentation catalysed by?
what’s lactate fermentation catalysed by?
🦎🦜🧪💐🩷
ethanol: ethanol dehydrogenase
lactate: lactate dehydrogenase
what is pyruvate first converted to before ethanol?💕
(in ethanol fermentation)
ethanal
what is the net gain in glycolysis?🐬
2 ATP, 2 NADH, 2 molecules of pyruvic acid
in glycolysis, how many ATP’s are produced, and how many are used?🩷
4 produced, but 2 used
what are the 2 aerobic respiration reactions?🎀
link reaction and krebs cycle
where does the krebs cycle occur🐈⬛
mitochondria matrix
what are the products of the krebs cycle?🫶
3 NADH, 1 ATP, 2 CO2, 1 FADH
how many turns of the krebs cycle does each glucose have?
what does this mean for the quantities per glucose?
🌊🏝️💓
each glucose has 2 turns of the krebs cycle so the quantities are doubled per glucose
what is the initial product of the link reaction?
what do we combine this with?
ultimately what is now formed?
💓💓💓
acetic acid
combined with coenzyme A
forms acetyl COA
there are 3 compounds involved in the krebs cycle.
how many carbons do each contain?💞
4-carbon compound
6-carbon compound
5-carbon compound
does anaerobic or aerobic respiration occur in the absence of oxygen?
does glycolysis require oxygen or not?
☀️
anaerobic and glycolysis can both occur in the absence of oxygen
2 uses of lactate after it’s produced?🐆😌
-oxidised back to pyruvate in krebs + used in ATP production
-converted to glycogen for storage in the liver
