|---|---|
 autotroph | organism that makes its own food |
| photosynthesis | process by which plants use the sun's energy to convert water and carbon dioxide into sugars |
| producer | organism that makes its own food and produces organic molecules that serve as food for other organisms in its ecosystem |
| heterotroph | organism that obtains food by eating other organisms |
| consumer | organism that obtains food by eating producers or other consumers |
| cellular respiration | chemical process that uses oxygen to convert energy in organic molecules into ATP |
| kinetic energy | energy of motion |
| potential energy | energy stored due to an objects position or arrangement |
| thermal energy | total amount of energy associated with the random movement of atoms and molecules |
| chemical energy | potential to perform work due to an arrangement of atoms within molecules |
| calorie | amount of energy required to raise the temperature of 1 gallon of water 1 degree Celsius |
| ATP | ADP+P=___ |
| ATP | Main energy source that cells use for most of their work |
| adenosine | consists of a nitrogen containing compound called adenine and a five-carbon sugar called ribose |
| 3 phosphate groups | a triphosphate tail consists of # ____ groups. |
| negatively | a phosphate group is ____ charged. |
| main types of cellular work driven by ATP | chemical work, mechanical work, transport work |
| metabolism | all of a cell's chemical processes |
| gycolysis | the splitting in half of a glucose molecule; the first stage of cellular respiration and fermentation |
| krebs cycle | stage of cellular respiration that finishes the breakdown of pruvic acid molecules to carbon dioxide, releasing energy |
| ATP synthase | protein structure in a cell mitochondria that uses energy from H+ ions to convert ADP to ATP |
| hemoglobin | protein that binds the bonds oxygen and CO2 |
| muscle fiber | parallel to one another, tiny tubes, many nucleus, made up of myofibrils |
| myofibrils | does contractions in muscles |
| 1. calcium ions are released from cell 2. tropomyosin falls off of actim 3. ATP bonds to mysosin head to make it change shape 4. ADP causes it to bond with the actim and pulls it shorter 5. releases ADP | muscle contraction steps |
| aerobic | requiring oxygen |
| electron transport chain | sequence of electron carrier molecules that transfer electrons and release energy during cellular respiration |
| glucose +O2 --> CO2 + H2O + ATP | cellular respiration equation |
