Fat is a substrate on which our body depends during aerobic training for metabolism.
Explanation: Aerobic literally means "with oxygen", and refers to use of oxygen in muscles' energy generating process. In such exercise, Oxygen is used to "burn" fats and glucose in order to produce Adenosine triphosphate the basic energy carrier for all cells. Initially during aerobic exercise glycogen is broken down to produce glucose, but in its absence, fat metabolism is initiated instead. The more efficient your body becomes through exercise, the easier it is for your body to convert fat into fuel. Fat allows to sustain our workouts for a long duration to see weight loss, cardiovascular and stress-reducing exercise benefits
As a result of long term aerobic training the body tends to depend more on __<u>Fat</u>__ as a substrate for metabolism.
<u>Explanation:</u>
Firstly, at the beginning of the training the body tends to depend on carbohydrates, because it's the easiest substrate to breakdown and give energy.
Fats breakdown gives more energy but it takes more time to breakdown, it's not easy like carbohydrates
In case of long term aerobic training, there will be no more carbohydrates to breakdown and the body tends to depend on fats to cover its need for energy.
Water diffuses into the skin via sweat ducts which alters the electrolyte balance. electrolytes can be salts like sodium and potassium. This alters the stability of neurons causing blood vessels to constrict therefore decreasing the amount of fluid in the fingers which would normally give the skin tension. The decrease causes wrinkles.
The effect would be that the green leaves, which contain chloroplasts, containing a chemical called chlorophyll would enable the plants to take in more energy in the form of sunlight, enabling the plants to photosynthesise and grow.
