what is metobolism?

Answer 1

Sum of the physical and chemical changes that take place in living organisms. These changes include both synthesis (anabolism) and breakdown (catabolism) of body constituents. In a narrower sense, the physical and chemical changes that take place in a given chemical substance within an organism. It includes the uptake and distribution within the body of chemical compounds, the changes (biotransformations) undergone by such substances, and the elimination of the compounds and their metabolites.

Answer 2

1. The complex of physical and chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.

2. The functioning of a specific substance, such as water, within the living body is also called metabolism.

Answer 3

What is Metabolism?
If you know what mpg (miles per gallon) means, then you already know what Metabolism means! Metabolism is simply the amount of calories that our bodies burn per day, just like the amount of miles we get per gallon of gas in our car.

Think of your Metabolism in this manner:

Vehicle = Your Body

Gas = Food

Oil = Vitamins & Nutrients Necessary for Optimum Nutrition

Water = Water that you intake daily

Ticket = Weight gain (oh no!!)

What is your Base Metabolic Rate (BMR) mean?

Think of your car again... Even when your car is idling it must have gas to run. In fact, without gas your car won't even start.

'Gas' represents our food intake. 'Food Intake' can also be thought of as 'energy'. Whenever we blink our eyes, turn our heads, lift our arms, smile or cry - we expend 'energy'. Even tooting expends energy. And what creates energy? That's right - FOOD!


Does your car use as much gas when it idles as when you are driving? No - of course not. Our bodies work the same way. When we are inactive, we use far less 'gas' but we still need 'gas' to run. And unlike our cars and trucks, our bodies are constantly running internally!

How fast is my Metabolism?

Think of your car again... A small car may get many miles per gallon whereas a larger car will get far less. Kids expend a tremendous amount of energy because they are growing and are generally very active.

The speed of your Metabolism is influenced by many things such as:

Age

Activity level

If you are male or female - men have more lean muscle tissue contributing to a 10% - 15% faster Metabolism than females

The amount of muscles that you have - muscle takes more calories to maintain than fat.

The old genes

Answer 4

The sum of the chemical reactions occurring within a cell or a whole organism involving the energy-releasing breakdown of molecules (catabolism) and the synthesis of newly particular fasioned molecules (anabolism).

Answer 5

-the series of processes by which food is converted into the energy and products needed to sustain life

-the biochemical activity of a particular substance in a living organism

Answer 6

Metabolism refers to the sum total of the biochemical reactions in your body (or another organism's body) that allows it to be maintained.

Some biochemical reactions are producing energy....other biochemical reactions are using up that energy. All with the purpose of either growth of the organism, reproduction of the organism or, eventually, the shutting down of that organism.

Answer 7

It is how fast yur body absorbs the food you eat and spreads it around your body continuing the cycle.
Some people have fast metabolism and some have slow, the faster the better.

Answer 8

The sum of all the chemical processes in the body.

Answer 9

The sum of all the chemical processes in the body.

Answer 10

the breakdown of the complex substances in ur diet , into simpler ones ; as well as the formation of new complex molecules in ur body from simpler elements , is termed as metabolism.
