When the cells in your body do not work correctly, homeostatic balance is disrupted. Homeostatic imbalance may lead to a state of disease. Disease and cellular malfunction can be caused in two basic ways: by deficiency (cells not getting all they need) or toxicity (cells being poisoned by things they do not need).
If total food calories exceed daily energy expenditure, excess calories accumulate as <u>fat in adipose tissue</u>
Explanation:
Calories is the measurement of energy released when the food is digested.
Proteins, carbohydrates and fats get digested to release energy.
Proteins and carbohydrates yield approximately equal amount of energy on getting digested. While fats yield maximum amount of energy.
If the amount calories produced by digestion of food exceeds the total amount of calories used up then the excess calories are stored as fats in the adipose tissue of the body.
This is the major reason why overeating and decreased physical activities results in obesity.
Just like any ecosystem, a self-sustaining ecosystem needs light for primary production and nutrient cycling. The environment must find an ecological balance and be able to support the survival and reproduction of all organisms living inside it
Fermentation occurs only when there is not sufficient oxygen available to permit aerobic reactions. (Note, this isn’t pictured in that overall picture at the top of this post).
Let’s pretend your muscles don’t have enough oxygen to attach these “hot potato” hydrogens onto oxygen. The NAD will then reattach these hydrogens back onto the middle carbon of each pyruvate to create lactic acid. The same way pyruvate is known as pyruvic acid, lactate is also called lactic acid, they are the same thing.
