Lipids are organic macromolecules that serve a variety of purposes what is the important role of lipids?
To store energy
What are the functions of the plasma membrane in Eukaryotes?
Plasma membrane gives structure to the cell, serve as boundary. It allows the selective passage of molecules across the cell (semi permeable). Starts the signalling event from the receptors it posses on the membrane surface when there is a stimuli bind to it.
How are the properties of phospholipids important in membrane functions?
Phospholipids are really just fat cells that exist in our membranes. They serve two very important functions. The most important are they help with temperature control. When the membrane gets cold, the phospholipids keep the membrane from freezing and becoming stiff, and when it gets too hot, they keep the cells form sticking together and melting
Why is catalytic activity of enzymes essential to ensure and regulate cellular metabolism?
Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane. Without enzymes, many metabolic reactions would not be able to be conducted efficiently, if at all.

What other main functions do proteins serve?
as enzymes to control the rate of reactions and regulate cellular activity
What different roles and functions do membrane proteins serve?
Membrane proteins relay signals between the cell's internal and external environments. They transport proteins and move molecules and ions across the membrane. They have many activities such as oxidoreductase, hydrolase or transferase.

In the membrane of a cell channels serve as what?
In the membrane of a cell, channels serve as passageways.

What two functions do barrier islands serve?
what two functions do barrier island serve
What does Endoplasm do?
They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins.
