Flippase and scramblase play important roles in the movement of lipid molecules across a membrane bilayer. Match each characteristic with its associated phospholipid translocator.- **Flippase** [Empty Box]- **Scramblase** [Empty Box] **Answer Bank**- provides headgroup randomization- ATP-independent- P-type ATPase- directional movement from outer leaflet to cytosolic leaflet- relocates phosphatidylethanolamine and phosphatidylserine- activity correlated to cytosolic calcium ion levels- movement dependent on concentration gradient- present in endoplasmic reticulum- ATP-dependentThe image consists of a list of statements or attributes typically related to biochemical processes, particularly those concerning membrane transport and ATPase activity. These phrases might be used in a context discussing membrane dynamics, phospholipid translocation, and calcium ion signaling. Each element of the list might describe a characteristic of specific proteins or cellular processes.

Aldosterone is a steroid hormone that freely enters the target cells to act within the cell. Epinephrine is a polar monoamine (amino acid) hormone that interacts with receptors on the cell's surface. What accounts for this difference? [Select any/all that apply.] Steroids are charged and hydrophilic, so aldosterone passed through a transport protein. Steroids are hydrophobic so aldosterone passed through the membrane by simple diffusion. Epinepherine (amino acid) hormone is hydrophilic, so it cannot diffuse through the phospholipid bilayer. Epinepherine (amino acid) hormone could diffuse through the phospholipid bilayer but it is attracted to the receptor protein.
The plasma membrane has a hydrophobic interior due to the two present in each phospholipid found in the phospholipid bilayer of the cell membrane. The plasma membrane allows some molecules to cross but not all. Therefore, the plasma membrane is said to be Molecules that are nonpolar and hydrophobic will cross the membrane with ease by Does this process require energy? When molecules move across the plasma membrane by passive transport, they will move down or with the_ from an area of concentration to an area of. concentration. Polar, hydrophilic molecules and charged ions will move across the plasma membrane by the process of_ This does not require energy, but it does require a A special case of diffusion is known as which is the movement of water across the plasma membrane.
