The reactions of glycolysis are made up of ten steps, out of the ten step three are irreversible, this is because, these reactions have large negative free energies The three steps that are irreversible are:
1. Phosphorylation of glucose.
2. Phosphorylation of glucose 6 phosphate and
3. Transfer of phosphate from phosphoenolpyruvate to ADP.
Answer:
A. He has a large buildup of lactate in his muscles.
Explanation:
Ideally, our body cells, via the process of aerobic cellular respiration, need oxygen to break down glucose. However, during rigorous activities or exercises, oxygen can become unavailable for use. In this case, the body cells switch to use another way of cellular respiration, which is FERMENTATION.
This fermentation causes a build up of lactic acid/lactate (its byproduct) in the cells of the muscles being used, which physically causes a burning and aching sensation just as the case of this hiker. The climbing of the steep path is causing causing the fast usage of oxygen in his cells.

In gilled mushrooms, gills are used to maximize spore production. Gills of some mushrooms are folded and crowded to obtain maximum spore production. Other gills, spread towards the outer cap which gives way to new gill growth in between gills which is called partial gill. Some of the mushrooms grow gills in layers too.
