T#6 Metabolism
This stack includes both terms/defs AND "target practice" with images.
| Term | Definition |
|---|---|
| rate | a comparison of two quantities that shows what happens to one when the other increases or decreases |
| slope | the 'steepness' of a line on a line graph…the steeper the slope the faster the rate of change |
| energy | the ability to do work (doesn't take up space and doesn't have mass) |
| chain molecule | a group of simple molecules chemically bonded together |
| simple molecule | a group of atoms chemically bonded together |
| atom | the smallest piece of an element |
| chemical bond | connection that holds atoms together to form molecules |
| chemical reaction | when atoms or molecules are rearranged and new substances are produced and energy is released or stored in the process |
| reactants | name for substances at the beginning of a chemical reaction (before they react) |
| products | name for substances at the end of a chemical reaction (after they have reacted) |
| arrow | the "yields" sign in a chemical equation...points to what new substances will be made in the reaction |
| triangle | the "delta" sign in a chemical equation…means "change in" whatever is being talked about |
| metabolism | all the chemical reactions that take place inside a living organism |
| anabolism | part of metabolism that involves using simpler molecules to build more complex molecules (and store energy in the process) |
| catabolism | part of metabolism that involves breaking more complex molecules down in to simpler molecules (and release energy in the process) |
| photosynthesis | chemical reaction that takes place in the chloroplasts of producers to produce sugars as a food source |
| respiration | chemical reaction that takes place in the mitochondria of both consumers and producers which releases the energy trapped in sugars |
| biological molecules | the four basic building blocks of living things: carbohydrates, proteins, lipids, and nucleic acids |
| carbohydrate | biological molecule that is the main chemical used to release energy in mitochondria |
| lipid | biological molecule that is used to make cell membranes and for storage of chemical energy |
| protein | biological molecule that is used to build cell parts and to do jobs for the cell |
| nucleic acid | biological molecule that stores the codes for how to make and run the cell |
| chemical indicator | a liquid that changes color or appearance when mixed with certain substances |
