Foods That Cause Plaque Buildup in the Arteries The Power of Food. Certain foods can cause the body to make too much of a waxy substance called cholesterol. Cholesterol can combine with fat, calcium, and other substances in the blood to form plaque. Plaque then slowly builds up and hardens in the arteries, causing them to narrow.This buildup of plaque, a condition called atherosclerosis, can lead to heart disease, heart attack, and stroke.he Power of Food.

Biochemistry/Membranes and Lipids Membranes And Lipids[edit] All cells, from simple prokaryotic bacteria to complex multicellular organisms are surrounded by a membrane. The membrane acts as a selective barrier, letting some substances into the cell and preventing other substances from entering. The membrane also actively transports substances between the inside and outside of the cell, using cellular energy to do so.

Membrane noun, plural: membranes. (1) (biology) A thin layer of tissue covering a surface or lining a cavity, space or organ. (2) (biology) A cell membrane. (3) (chemistry) A thin pliable sheet of material that is permeable to substances in solution. A biological membrane functions by protecting the surface or bodily organ. It acts as a barrier against injurious substances. It also acts as a film or covering separating two regions. It may also connect structures or organs of an animal or a plant.

Membrane A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Biological membranes include cell membranes (outer coverings of cells or organelles that allow passage of certain constituents);[1] nuclear membranes, which cover a cell nucleus; and tissue membranes, such as mucosae and serosae.

cell membrane cell membrane. A cell membrane is like a cell's gatekeeper. It's the outer layer that surrounds a cell, letting substances in — or keeping them out. A membrane is a barrier that offers protection, like a rubber membrane that keeps rain from seeping under your roof. A cell membrane surrounds and protects the contents of a cell. It controls which substances can enter and exit the cell. The membrane also gives a cell its shape and enables the cell to attach to other cells, forming tissues.
