Cellular Metabolism and Molecule Building: Importance of Food

TermDefinition
Metabolism the chemical processes that occurs within a living organism in order to maintain life.
Energy the ability to do work
Nutrients components in food that the body needs to grow, develop and repair itself
Macronutrients nutrients that organisms must ingest in a large amount to maintain health
Enzyme a special class of proteins that speed up biological reaction by lowering the energy needed to start the reaction; known as the energy of activation; tools of the cell
Catalyst a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
Activation Energy the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
Active Site a region on an enzyme that binds to a protein or other substance during a reaction.
Catabolic Reaction destructive metabolism; the breaking down in living organisms of more complex substances into simpler ones, with the release of energy
Anabolic Reaction constructive metabolism; the synthesis in living organisms of more complex substances from simpler ones
Denature to treat (a protein or the like) by chemical or physical means so as to alter its original state.
Digestive system the system by which ingested food is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products
Mechanical Digestion Food is broken down by chewing, biting and tearing
Chemical Digestion Food is broken down by enzymes
Mouth Chews food into smaller bits
Pharynx swallows
Salivary Glands breaks down starch into sugar through chemical digestion; salivary amylase
Esophagus peristalsis; cardiac sphincter
Liver makes bile; largest organ
Gull Bladder stores bile; attached to liver
Stomach pepsin; hydrochloric acid; mucus
Small Intestine most chemical digestion happens; absorbtion; every macromolecule is broken down here
Pancreas makes enzymes, carbs, lipids and bicarbonates
Large Intestine absorbs water and vitamins; produces vitamins B and K

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
