What produces lipids for the cell membrane?
smooth er produces lipids and takes part in drug detoxification
A cell membrane is composed of what?
The cell membrane is composed of the lipid bilayer. In addition to lipids most membranes contain proteins and carbohydrates. ________________________________________________________________ YOUR finger nails and hair are made out of Keratin. its a protein (so is whale baleen and animal horns)
Prokaryotic cells lack a what while what cells contain a nucleus?
Prokaryotic cells lack a definite nucleus and membrane- bound organelles while eucaryotic cells have a definite nucleus.
Describe a structure of life cycle of amoeba and paramecium?
Parmamecium has a definite shape and slides through water while Amoeba is a single celled organism that has no definite shape and consisting of a mass of protoplasm containing one or more nuclei surrounded by a flexible out membrane. Parmamecium has a definite shape and slides through water while Amoeba is a single celled organism that has no definite shape and consisting of a mass of protoplasm containing one or more nuclei surrounded by a flexible out membrane.
How are the two sides of the cell membrane different?
1. The two lipid layers may differ in specific lipid composition, and each protein has directional orientation in the membrane. The plasma membrane also has carbohydrates, which are restricted to the exterior surface. This asymmetrical distribution of proteins, lipids, and carbohydrates is determined as the membrane is being built by the ER end up on the outside face of the plasma membrane.
What are two types of glycocalyx found on bacteria?
Glycocalyx consists of the carbohydrate moieties of membrane glycolipids and glycoproteins.
Short chains of sugars attached to recognition proteins in the cell membrane make up the?
Glycocalyx
What is the layers on the outside of a cell membrane called?
The layer outside the cell membrane is the cell wall.
What are two factors in addition to special membrane junctions that help hold cells together?
Glycoproteins in the glycocalyx and wavy contours.
Do bacteria lack a definite nucleus and have no nuclear membrane?
Yes,they lack a definite nucleus.So they lack a nuclear membrane.
What produces lipids for the cell membrane?
smooth er produces lipids and takes part in drug detoxification
Is the glycocalyx is often referred to as the cell coat which is somewhat fuzzy and sticky with numerous cholesterol chains sticking out from the surface of the cell membrane .true or false?
false.
What is prokoaryote?
A prokaryote is a single-celled organism with no definite nucleus and no definite nuclear membrane. Compared to a eukaryote which can be single-celled or multi-cellular and has a true nucleus with a nuclear membrane.
What is the answer of euglena?
they cinsist of a membrane that allows them to keep a definite shape but also make adjustment

What are meningiomas?
Meningioma's are tumors in the meninges, the membrane that surrounds the brain and spinal cord. Most meningioma's are benign though they can rarely be cancerous.
What makes up a glycocalyx and its function?
The glycocalyx is the outer layer of a bacteria cell. It helps the cell "stick" to other cells and other objects, as well as retain water. Its a gelatinous sticky substance that surrounds the outside of the cell for Prokaryotes. If the glycocalyx (singular) is composed of repeating organic subunits tightly affixed to the cell wall its nomenclature changes to, Capsule. The loose, water soluble glycocalyx is named, Slime Layer. Both prevent desiccation (drying out). For pathogenic bacteria, the glycocalyx provides a means for survival and the ability to attach to other cells and cause disease. Hope this helps.
