1) You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described?
2) What are peripheral membrane proteins?
In the figure below are several panels that illustrate the relative concentration of a particular solute on either side of a cell's plasma membrane. The top panel represents the INITIAL (or starting) scenario, and the lower panels represent different possible outcomes after time has passed.

- The primary function of the kidney is to exchange molecules across a membrane between the blood and the urine. One type of kidney cell has a basic rectangular shape, except for a single surface, which is lined with tiny, finger-like projections that extend into the surrounding extracellular space. Which of the following best explains the advantage these projections provide the cell? The projections increase the selectivity of the membrane because the small size of the projections limits the number of transport proteins that can be embedded in the membrane. The projections increase the volume of the cell without affecting the surface area, which increases the metabolic needs of the cell. The projections increase the surface area–to-volume ratio of the cell, which allows for more efficient nutrient exchange with the environment. The projections increase the speed at which an individual molecule can move,…arrow_forwardCompare and contrast the following methods of a passing cell membrane in terms of movement with respect to the concentration gradient, use of ATP, and the use of transporters with examples.

- How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.arrow_forwardResearchers tried to explain how vesicular transport occurs in cells by attempting to assemble the transport components. They set up microtubular tracks along which vesicles could be transported, and they added vesicles and motor protein kinesin.

- Compare and contrast the following methods of a passing cell membrane in terms of movement with respect to the concentration gradient, use of ATP, and the use of transporters with examples. (Simple) diffusion vs Facilitated diffusionarrow_forwardThe surface area to volume ratio affects the ability of the cell to exchange nutrients and waste products with the outside environment. Many factors affect the movement of molecules across the cell membrane, including membrane thickness, temperature, pressure, concentration gradient, molecular mass, distance travelled, solvent properties and surface area of the cell. In general, according to Einstein’s approximation equation (Equation 1), diffusion time is inversely proportional to the to the diffusion coefficient (D), where t is time and x is distance travelled. The diffusion coefficient is unique to each type of molecule and is determined experimentally. Waste products such as carbon dioxide (CO2) pose a unique problem to cells as their accumulation may be lethal. Exchange with the external environment is dependent upon the distance the waste must travel; for a round cell this will be up to half the cell diameter. Using the diffusion coefficient (D) for carbon dioxide (1.97 × 10-5…arrow_forwardLiver cells are in contact with the blood and exchange a variety of substances with the blood plasma (the noncellular part of blood). The concentration of water is equal in the cytoplasm of liver cells and in the blood plasma. Explain this observation in terms of membrane permeability and transport mechanisms. Animal cells typically maintain a higher concentration of Na+ outside the cell and a higher concentration of K+ inside the cell via the Na+-K+ pump. The drug ouabain inhibits the activity of the Na+-K+ pump. A nerve cell is incubated in ouabain. Predict what will happen to the concentrations of Na+ and K+ inside and outside the nerve cell as a result.arrow_forward
