Answer:
C Ribose
Explanation:
The sugar is the ribosoe, Ribose is the sugar in the backbone of RNA, ribonucleic acid.
Answer:
- flippases translocate lipids from outer (extracellular) leaflet to inner (cytosolic) leaflet,
- floppases, move phospholipids from inner (cytoplasmic) leaflet to outer (extracellular) leaflet, ABC transporter, move phospolipids across the lipid bilayer down the concentration gradient
- scramblases Not ATP-dependent, Activation may result in increased membrane lipid symmetry, translocate phosphatidylserine, preventing apoptosis and engulfment by macrophages,
Explanation:
Flipases are transportes that require energy for their functioning (ATP dependent) beause they move phospolipids across the lipid bilayer against the concentration gradient (from extracellular side to cytosolic side).
Floppases are ABC transporters, opposite than flippases (move phospholipids from the cytosolic side).
Scrablases are bidirectional transporters, responsible for asymmetry formation. It also enables exposure of phosphatidylserineon the outer leaflet when it is necessary.
Explanation:
B) Molecules are moving from a higher concentration to a lower concentration
Water molecules from the more concentrated side, will flow into the less concentrated side til they equilibrate- at equilibrium both sides will have the same concentration of solute and water molecules.
In diffusion, small non-charged molecules can move from regions of high concentration to regions of low concentration. This occurs across the phospholipid bilayer, which acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic- this involves the movement of water molecules, gases or other small water-soluble compounds
.
In osmosis, molecules of water move across a semi permeable membrane, from regions of high concentration to regions of low concentration until an equilibrium is reached. This always occurs along the concentration gradient within the system.
