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 |
