Concept explainers
Introduction:
All living organisms are made up of cells and its products. Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).

- 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_forwardA transport protein requires ATP to pump sodium ions across a membrane. This is a case of ______. a. passive transport b. active transport c. facilitated diffusion d. a and carrow_forwardThe principal force driving movement in diffusion is______. a. temperature b. particle size c. concentration gradient d. membrane surface areaarrow_forward
- The passive non-mediated movement of particles across a membrane driven by pressure is A. filtration B. diffusion C. facilitated diffusion D. osmosis E. active transport F. vesicular transportarrow_forwardGlucose is often present in very low concentrations in environments populated by microorganisms. To import the maximum amount of available glucose, cells use a. Receptor-mediated endocytosis b. Simple diffusion c. Osmosis d. Facilitated diffusionarrow_forwardFor 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_forward
- one 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_forwardChoose which substances can pass freely through the plasma membrane A. Gasses B. Charged molecules C. Hydrophobic molecules D. Lions E. Water D. ATParrow_forwardLiver cells in culture were kept at 0°C and treated with trypsin to digest the receptors on the cell surface. The temperature was then raised to 37°C and radioactive LDL was added to the culture media. Several hours later, the labeled LDL was found to be inside the cells. This specific process of LDL uptake is A. active transport B. facilitated diffusion C. phagocytosis D. pinocytosis E. receptor-mediated endocytosisarrow_forward
- A genetic mutation that results in abnormal stimulatory G protein (Gs) structure would adversely affect which of the following mechanisms? A. Active transport B. Facilitated diffusion C. Pinocytosis D. Receptor-mediated endocytosis E. Signal transduction L H 12 W Parrow_forwardWhich is common between active transport and facilitated diffusion A Both uses metabolic energy B Both processes happen with the aid of transport proteins C Both of them transport molecules from lower to higher concentration D Both of them transport molecules from higher to lower concentrationarrow_forwardMovement of cell against concentration gradient is called: A. osmosis B. active transport C. diffusion D. passive transportarrow_forward
