Concept explainers
The organism is the individual entity that embodies the properties of life. It is classified into unicellular organism such as protists, bacteria and archaea and multicellular organism such as plants, animals and fungi.
The cell is the basic, fundamental and biological unit all living organism. It consists of many internal structures called organelles that are embedded in the semifluid called as cytoplasm. The organelles are nucleus, Golgi apparatus, lysosomes, mitochondria, chloroplast endoplasmic reticulum. Each of the organelles performs specific functions within the cell. The cells are covered by the outer covering called as plasma membrane in animals whereas in plants it is covered by cell wall made up of cellulose.

- So I know that Dapagliflozin is a inhibitor of the sodium glucose cotransporter so does Dapagliflozin cause glucose to just stay in the cell or does it cause glucose to exit the cell? Also if does cause glucose to exit the cell is this a passive or active process. I would think that it would be passive since the glucose is going from high to low?? So is it faciliated passive diffusion?? Please help I am not sure if I am on the right track or not I could be totally wrong so please correct me.arrow_forwardRebuild the cell above that is hypertonic to the solution outside. By hitting the red button, add 20 solutes (green) to the inside of the cell and add 5 water (blue) to the inside of the cell. Also, add 20 water (blue) to the outside of the cell and 5 solutes (green) to the outside of the cell. Add blue gated channels to the membrane. Q: What happens to the water molecules in this situation? Q: Which of the above situations is closer to a living membrane system?arrow_forwardYou are viewing two samples of mammalian red blood cells (erythrocytes) under a microscope. One first sample is made up of cells with a typical round shape. Most of the cells in the second sample had burst open. •Describe the properties of the solution that was used to prepare the second sample. • Identify one type of solute that can move through simple diffusion and does not affect osmotic pressure or require a membrane protein to cross a plasma membrane.arrow_forward
- Explain/compare the following:totipotent vs pluripotent vs multipotent cellsarrow_forwardOxygen gas (O2) is a small nonpolar molecule. What is the transport mechanism for oxygen to cross the plasma membrane? Group of answer choices diffusion facilitated diffusion osmosis active transport endocytosisarrow_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_forward
- Which of the following involves the use of protein macromolecules to cross the plasma membrane simple diffusion facilitated passive transport active transport both facilitated and active transportarrow_forwardwhich cell structure would play a role in cell migration? phospholipid bilayer peripheral protein serving as an enzyme intercellular joining between two body cells integral protein serving as a carrierarrow_forwardSeveral factors influence the diffusion rate of substances across plasma membrane. A decrease in ___ will increase the rate of diffusion of a substance across a plasma membrane. Temp Steepness of concentration gradient The mass of the diffusing substance The membrane surface area available for diffusion which one is correct?arrow_forward
