Anatomy ch 3 and 4
| Question | Answer |
|---|---|
| Pyrimidines in DNA | Cytosine and Thymine |
| Types of Vesicular Transport | Exocytosis and Endocytosis |
| Types of Active Transport | 1) Ion pumps 2) Secondary Active transport |
| types of active membrane processes | 1) active transport 2) vesicular transport 3) trans-membrane potential |
| facilitated diffusion | - carrier proteins are used as a mechanism - no energy required |
| diffusion | movement of substances from a high to low concentration |
| selectively permeable | allow only some substances through |
| permeable | anything crosses, with ease |
| impermeable | nothing passes through |
| membrane permeability | effectiveness as a barrier |
| DNA shape | double stranded helix |
| RNA shape | varies, normally single stranded |
| DNA nucleotides | over 45 million |
| RNA nucleotides | 100-50,000 |
| RNA pyrimidines | Cytosine and Uracil |
| RNA purines | Adenine and Guanine |
| DNA purines | Adenine and Guanine |
| DNA sugar | deoxyribose |
| RNA sugar | ribose |
| RNA | part of protein synthesis machinery |
| DNA | carries genetic info needed to synthesis every protein in the body |
| Types of nucleic acids | DNA and RNA |
| Potential can be changed Via.. | changes in pressure, temp, and chemical environment in and out of the cell |
| transmembrane potential | separation of positive and negative charges across a membrane |
| responsible for flow | exocytosis and endocytosis |
| Phagocytosis | solid incoming, cell eating |
| pinocytosis | fluid incoming, cell drinking |
| ligand | targets extracellular molecules |
| receptor-mediated endocytosis | specific molecules are signaled to enter cell via presence of specific receptors at membrane surface |
| forms of endo cytosis | receptor mediated endocytosis, pinocytosis, phagocytosis |
| Endocytosis | movem |
