The given statements can be matched as following:
a)The diffusion of water from a high concentration to a low concentration - Osmosis
b)Lowers the amount of energy needed to perform chemical reactions
- Enzymes
c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream
-Simple Diffusion
d)Involved with, but does not become a part of chemical reactions
-Enzymes
e)Small molecules with no charge can move through semi-permeable membranes by this process-
Simple Diffusion
Explanation:
a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.
b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.
c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.
d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.
e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.
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.
