| Define Effectors | organs that directly influence controlled physiological variables |
| Extrinsic control usually involves which mode of regulation? | Nervous and Endocrine |
| Define afferent | a signal traveling toward a particular center or point of reference |
| Whats ATP mde of Adenosine triphosphate (ATP) | - composed of an adenine and ribose sugar (a combination called adenosine) to which are attached a string of three phosphate groups |
| Factors that causes Protein to denature | - Change in temperature -change in pH -radiation -certain hazardous chemical |
| 3 types of Carbohydrates | 1. Monosaccharides (simple sugars) 2. Disaccharides (double sugars) 3. Polysaccharides (complex sugars) |
| Nucleic Acid | A very large molecule composed of subunits of sugar, a nitrogen base, and a phosphate bond |
| Whats Catalyst | a chemical that reduces the amount of activation energy needed to start a chemical reaction |
| Anabolism | Builds up large complex molecules from small one to large ones |
| Catabolism | Breaks down molecule , usually nutrient molecules, and thereby releases energy from the broken molecules |
| Active transport | Molecule wants to go to low -> high concentration this is when ATP is used , it requires energy |
| Why is cartilage slow to heal. | -Because it has no or limited blood supply - flexible and semi solid |
| What is are the two types/functions of bone marrow? | Red & yellow – produces red blood cells and stores energy as fat. |
