- Active transport must function continuously because_______. a. plasma membranes wear out b. cells must be in constant motion c. facilitated transport opposes active transport d. diffusion is constantly moving the solutes in the other directionarrow_forwardWhich of the following methods of transport is being used to transfer the substance into the cell in the accompanying graph? a. diffusion down a concentration gradient b. osmosis c. facilitated diffusion d. active transport e. vesicular transport f. It is impossible to tell with the information provided.arrow_forwardMatch the following with the term that best describes them integral part of the plasma membrane can easily cross the semi-permeable plasma membrane cellular currency of cell that enables it to transport molecules against the concetration gradient (i.e active transport) act as channels carriers to transport polar molecules like sugars into cells A. phospholipids B. proteins C. ATP D. oxygenarrow_forward
- What is the Description and Examples in the body of these Cell transport? Explain in 2-3 sentencesDescription:Examples in the body: 1. Bulk Transport 2. Phagocytosis 3. Pinocytosis 4. Receptor-Mediated Endocytosisarrow_forwardone reason active transport has a limited maximum transport rate at which it can progress is due to the fact that a. energy required is not available inside the cell b. carrier proteins are not on the surface of the cell membrane c. ion channels are limited in size d. the number of carrier proteins is limited and therefore they can become saturatedarrow_forwardChilling most directly affects a. nuclear proteins. b. vacuolar inclusions. c. the cytoskeleton. d. membrane lipids.arrow_forward
- For the following modes of transport for membranes, tell whether the flow is with or against chemical potenial. Meaning +deltaG or -deltag A. Passive Diffusion B.Faciliated Diffusion C.Active Transportarrow_forwardPLEASE ANSWER THE FOLLOWING QUESTIONS:arrow_forwardMatch the term with its correct description: a. energy b. facilitated diffusion c. endocytosis d. passive transport e. active transport f. exocytosis g. carrier protein h. channel protein Transport protein that provides a tube-like opening in the plasma membrane through which particles can diffuse Is used during active transport but not passive transport Process by which a cell takes in material by forming a vacuole around it Particle movement from an area of higher concentration to an area of lower concentration Process by which a cell expels wastes from a vacuole A form of passive transport that uses transport proteins Particle movement from an area of lower concentration to an area of higher concentration Transport protein that changes shape when a particle binds with itarrow_forward
- Movement of cell against concentration gradient is called: A. osmosis B. active transport C. diffusion D. passive transportarrow_forwarda. Substance X is transported by passive transport and Substance Y is transported by active transport b. Substance X is transported by active transport and Substance Y is transported by passive transport c. Substance X is transported by active transport and Substance Y is transported by active transport d. Substance X is transported by passive transport and Substance Y is transported by passive transportarrow_forwardChoose answer of the following The extracellular matrixa. assists in the movement of substances across the plasmamembrane.b. prevents the loss of water when cells are placed in a hypertonicsolution.c. has numerous functions that affect the shape and activities of thecell that produced it.d. contains the junctions that sometimes occur between cells.e. All of these are correctarrow_forward
