Which of the Following Statements Correctly Describes the Plasma Membrane

The diffusion of Na ions into the cell is facilitated by the Na concentration gradient across the plasma membrane. Signal recognition particle SRP is a complex of RNA and protein that guides the ribosomes into the translocons present in the plasma membrane where they form secretory protein and these proteins are transported through plasma membrane translocons.

Pumps move substances through the plasma membrane Pumps glue the plasma membranes of adjacent cells together. It is composed of phospholipid bilayer structure with embedded proteins. The following statements that correctly describes T tubules and their role in conducting action potentials in muscle cells are.

A The animal cell is in a hypotonic solution and the plant cell is in an isotonic solution. Therefore the correct answer is B. The diffusion of na ions into the cell is impeded by the electrical gradient across the plasma membrane.

Cholesterol enables the membrane to stay stable at high temperatures Cholesterol enables the animal to add hydrogen atoms to unsaturated phospholipids Cholesterol enables the membrane to become more rigid when cell temperature. In prokaryotes the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. Which of the following statements correctly describes osmosis- In osmosis water moves across a membrane from areas of lower so.
