Respiration is one of the biggest topics you will cover in A Level Biology-and it will come up in the exam, guaranteed.
The purpose of the Krebs Cycle is to release stored energy from a series of chemical reactions. In the exam you are expected to know all the little details:
a) acetyl-co-enzyme A reacts with a four-carbon molecule, releasing co-enzyme A
b) and produces a six-carbon molecule that enters the Krebs cycle in a series of oxidation-reduction reactions,
c) the Krebs cycle generates reduced coenzymes and ATP by substrate-level phosphorylation,
d) and carbon dioxide is lost.
This is for all A Level Biology AQA, OCR & Edexcel Students.

Why did you skip the vids for link reaction and Calvin cycle?

Isn't it FADH2 because FAD accepts 2 hydrogen atoms and not FADH

@armzfinna7981 5 жыл бұрын

reduced FAD will do

I'm writing an essay about responses and I found myself saying 'its important for the bacteria to respond to the harsh conditions in order to survive and therefore replicate because...' and I don't know how to finish the sentence. It's the same when I talk about humans, why is it important that we survive and reproduce? Any help would be much appreciated!

I guess the best answer for that is all living things are part of a huge ecosystem as one factor affects the another. In this case, some bacteria are helpful in the ecosystem in terms of the process of decomposition of some organic matter, which is then recycled in some ways by nature. Energy will always be in a cycle with nature, may it be in humans or bacteria.

We don't. Humans have overpopulated the world to the extent thousands of other species have become extinct.
