00:01 Let me want to answer this question.

00:02 Let's talk about metabolism.

00:04 Here you have a world bank and you have to complete the blanks here.

00:08 It says, complete a following paragraph to describe how atp is produced in the absence of oxygen.

00:12 Here you have complete glucose breakdown requires the presence of blank to keep the electron transfer chain working so that atp is produced.

00:20 Remember that the complete glucose breakdown is going to require oxygen in order for the electron transfer chain to work because this electron transfer chain is going to acquire oxygen that is a final electron acceptor.

00:32 So oxygen is going to be here and you have it here.

00:38 Oxygen.

00:38 Now here you have.

00:40 When blank is absent, an anaerobic process is called fermentation or curses instead producing.

00:47 So practically here we have to repeat this oxygen, okay? we have to repeat oxygen here.

00:52 When oxygen is absent, an anaerobic process called fermentation occurs instead.

00:57 Producing and when you don't have oxygen and fermentation is occured you're going to produce only two atp per glucose molecule okay and in those 80ps those two atps are produced from glycolysis so you're going to have here producing fewer atp overall fewer atp overall then you have during this process glycolysis proceeds as normal with glucose splitting into two and well pyruvate is going to be producing normally okay it means glycolysis is going to occur normally so glycolysis is going to produce what it normally produces it means pyruid here and another pyruvate here so you're going to produce into two pyruvate molecules which are then phosphorylated into two bpg molecules and finally converted into two lactate molecules okay in this case this is a this is lactic acid fermentation lactate molecules then you have here however at this point that two blank molecules are reduced freeing an ad plus to return the glycolate pathway...
