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.
Answer:
A flower can either be classified as a monocot or a dicot depending on the number of petals present on the flower.
Explanation:
- Monocot also known as monocotyledon are characterized by the presence of one sees leaf(cotyledon) inside the embryo
The seed leaf is often thin because the endosperm which is required to feed the young plant is not found inside the seed leaf. In monocot flower a the number of petals is 3 or a multiple of 3. Examples of monocot flowers include; Asparagales, Wedges, Bromeliads, Poles.
- Dicots also known as dicotyledons are flowering plants that have two seed leaf. In a dicot flower the number of petals is 4 or 5 or a multiple of 4 or 5. Examples of dicot flowers include; Roses, Magnolas, Sunflower, Geranium.
