Question
Endocytosis moves materials a cell via. into; facilitated diffusion into; membranous vesicles into; a transport protein out of, diffusion out of, membranous vesicles Which of the following structure-function pairs is mismatched? smooth endoplasmic reticulum: detoxifying poisons Golgi: protein trafficking (sorting) cell membrane: selective barrier smooth endoplasmic reticulum: phospholipid synthesis nucleus: protein synthesis The active site of an enzyme is the region that binds allosteric regulators of the enzyme. binds the substrate. binds the products of the catalytic reaction. is not influenced by pH both A and B Osmosis moves water from a region of to a region of. high concentration of dissolved material of concentration of dissolved material low concentration of dissolved high concentration of dissolved material hypertonic solution; hypotonic solution negative osmotic potential; positive osmotic potential low concentration of water; high concentration of water How does a non-competitive inhibitor decrease the rate of an enzyme reaction? By binding at the active site of the enzyme by changing the structure of the enzyme by changing the free energy change of the reaction by acting as a coenzyme for the reaction by decreasing the activation energy of the reaction Which of the following is not a known function of the cytoskeleton? to maintain a critical limit on cell size to provide mechanical support to the cell to maintain the characteristic shape of the cell to hold mitochondria and other organelles in place within the cytosol to assist in cell motility by interacting with specialized motor proteins What structures move proteins from the ER to the Golgi apparatus? lysosomes ribosomes transport vesicles peroxisomes nucleosomes Reactants capable of interacting to form products in a chemical reaction must first overcome a barrier known as the reaction's entropy activation energy. endothermic level. heat content. free-energy content.Explanation / Answer
13)B)into;membranous vesicles
14)B)Cell membrane :selective barrier
The basic function of thecell membrane is to protect the cell from its surroundings.
15)C)Binds the products of catalytic reaction
The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
16)A)High concentration of dissolved material ; low concentration of dissolved material .
In osmosis, water always moves from an area of higher waterconcentration to one of lower concentration.
17)B)by changing the structure of the enzyme.
18)E) to assist in cell motility by interacting with specialized motor proteins
cytoskeleton:A system of filaments found in the cytoplasm of cells and responsible for the maintenance of and changes in cell shape, cell locomotion, movement of various elements in the cytoplasm, integration of the major cytoplasmic organelles, cell division, chromosome organization and movement, and the adhesion of a cell to a surface or to other cells.
