![]() ![]() The protein then changes shape, moving the molecule across the membrane and releasing it on the other side. They help maintain cell shape, adhere to and move along surfaces and form connections between adjacent cells.Īnswer: proteins that regulate the movement of hydrophilic molecules through the plasma membraneĪnswer: form channels whose central pores allow water molecules or specific ions to pass through the membrane along their concentration gradientsĪnswer: proteins that have binding site that can temporarily attach to specific molecules on one side of the membrane. Blood plasma is the straw-coloured/pale-yellow, liquid component of blood that typically holds the blood. Binding by receptor proteins typically triggers a response by a cell, such as endocytosis, increased metabolic rate, or cell division.Īnswer: a protein or glycoprotein protruding from the outside surface of a plasma membrane that identifies a cell as belonging to a particular species, to a specific individual of that species, and in many cases to one specific organ within the individual.Īnswer: proteins that promote chemical reactions that synthesize or break apart biological moleculesĪnswer: a protein in the plasma membrane of a cell that attaches either to the cytoskeleton inside the cell, to other cells, or to the extracellular matrix. intracellular lymphatic plasma cerebrospinal extracellular, About two-thirds of the bodys fluid is within cells and is termed fluid. ![]() ![]() The phospholipid heads, which are hydrophilic, face the water of extracellular fluid or the cytoplasm the tails, which are hydrophobic, are buried in the middle of the bilayer.Īnswer: A protein, located on a membrane or in the cytoplasm of a cell, that recognizes and binds to specific molecules. Our body fluids, mainly consists of intracellular fluid and extracellular fluid, bathe our tissues and organs with resources that are necessary for survival and collect the waste. Study with Quizlet and memorize flashcards containing terms like Homeostatic mechanisms that monitor and adjust the composition of body fluids respond to changes in the fluid. The extracellular fluid is mainly cations and anions. Enzymes in the cytosol are important for cellular metabolism. Answer: each membrane consists of a mosaic or “patchwork” of different proteins that constantly shift and flow within a viscous fluid formed by a double layer of phospholipidsĪnswer: a double layer of phospholipids that forms the basis of all cellular membranes. The cytosol or intracellular fluid consists mostly of water, dissolved ions, small molecules, and large, water-soluble molecules. ![]()
