- 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_forwardWhat is the difference between simple and facilitated diffusion? Facilitated by which type of molecule does the term “facilitated” mean?arrow_forwardDoes secondary active transport occur in the absence of primary active transport? yes or no and why or why not?arrow_forward
- 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?arrow_forwardFor each type of membrane transport, know the following:– Is a transporter protein required? If so, what type?– Is there an energy requirement, and if so, what is the energy source?– What is the relative rate of solute transport based on molecule type? On concentration gradient?– What are examples of the types of solutes transported by carriers and channels?arrow_forwardWhat type of transport is illustrated by the protein that simultaneously pump H+ and surcose across a membrane?arrow_forward
- What would happen in each of the following cases where something related to intracellular transport is altered? Assume in each case that the protein involved is a soluble protein, not a membrane protein. State where each protein would be located and explain each of your answers. You add a signal sequence (for the Golgi) to the N-terminal end of a normally cytosolic protein. You change the hydrophobic amino acids in an ER signal sequence into other, hydrophobic, amino acids.arrow_forwardWhat do diffusion and osmosis have in common? How are they different from active transport? In the nervous system, where can you find examples of each of these?arrow_forwardOne of the curves in this graph describes nonmediated diffusion, and the other describes facilitated transport. Which is which? Explain your choices.arrow_forward
- Which feature is typical of primary active transport? The transport protein must cross to the correct side of the membrane before the solute can bind to it. The transport protein is irreversibly phosphorylated as transport takes place. The transport protein catalyzes the conversion of ADP to ATP. The solute moves against the concentration gradient. A concentration gradient provides the energy to move substances against their concentration gradient.arrow_forwardWhat are the differences between sodium-potassium exchange pump and sodium-glucose transporter? Besides I am struggling with understanding the Vesicular Transport (Bulk transport) why it is a form of an active transport? Simple diffusion, facilitated diffusion and osmosis are all passive transport. What are the differences between them and how can be an active form??? And why not concentration gradient is not involving??? Because it utilise transport proteins like receptor mediator endocytosis. It might changes some gradients. Am I misleading some concepts??? Endocytosis and Exocytosis concepts are confusing too. Thanks for reading my question :D I am really confusing of the membrane transportarrow_forwardWhich of the following membrane transport mechanism requires both the aid of proteins and the expenditure of cellular energy?arrow_forward
