Respiration in Biology: Aerobic & Anaerobic Processes

[Peter G.]

The following represent two processes of energy production. The letters X and Y represent two products:

Process 1:

Glucose → Pyruvic Acid → Carbon Dioxide + X + 38 ATP - Happens with Oxygen​

Process 2

Glucose → Pyruvic Acid → Carbon Dioxide + Y + 2 ATP - Happens without Oxygen​

Questions:

a) Name process 1 and 2 as well as the substance X and Y
b) Name the living organisms that conduct each of the processes
c) Explain what would happen to an organism that performs the first process as he climbed a mountain, where there's less air:

My attempts:
a) Process 1 would be Aerobic Respiration while process 2 would be anaerobic respiration (or fermentation?), but I don't know if I have to go into further detail (any clues?)

X would therefore be water while Y would be Ethanol

b) Process 1 - Us, humans
Process 2: Deep soil bacteria

c) In such scenario, the organism would suffer from a lack of oxygen supply hence, having to switch to anaerobic respiration.

Thanks,
Peter G.
