Cotransport Study guides, Class notes & Summaries

transport proteins - are responsible for controlling passage across the membrane fluid mosaic model - The membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids fatty acid tails - nonpolar, hydrophobic fatty acid heads - hydrophilic, polar periphial proteins - bound to the surface of the membrane integral proteins - penetrate the hydrophobic core (ones that span the membrane are transmembrane protiens How do cells recognize each other? - by binding to molec...

HUMAN ANATOMY AND PHYSIOLOGY NEWEST EXAM QUESTIONS AND CORRECT ANSWERS ALREADY GRADED A+. Hypotonic - ANSWER- net water movement into cell. Cells swell and lyse. Filtration - ANSWER- occurs along a pressure gradient (high pressure to low pressure). Not a selective process, common in kidney Active transport - ANSWER- Requires energy (ATP) for movement against a concentration gradient, from low to high sodium-potassium pump - ANSWER- used to establish membrane potential. Energy (A...

hyllotaxy - the arrangement of leaves on a stem, is specific to each species. leaf area index - the ratio of total upper leaf surface of a plant divided by the surface area of land on which it grows self-pruning - Non-productive leaves in a crop or plant go through programmed cell death (apoptosis) and are shed to increase productivity of other leaves Passive transport - The movement of substances across a cell membrane without the use of energy by the cell - diffusion Active transport - ...
