What does it mean to say most biological membranes are selectively permeable?
Selectively permeability is a property of biological membranes that allows them to regulate the passage of substances across them. In spite of heavy traffic through them, cell membranes are selectively permeable, and substances do not cross the barrier indiscriminately.
Materials essential to life processes move across a cell membrane through a variety of methods What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?
carrier proteins
What allows glucose molecules into cell?
Gluconeogenesis, the production of glucose, occurs only in the liver and the kidney cortex. The process begins in the mitochondria, but a majority of the biosynthetic reactions take place in the cytoplasm. The ultimate metabolite of the pathway produces glucose 6 phosphate, which is transported into the lumen of the endoplasmic reticulum and converted into glucose via the enzyme Glucose 6 Phosphatase. (Glucose is maintained as Glucose 6 phosphate to prevent it escaping from the cell.)
Why does water exit the blood by filtration but reenter by osmosis?
Through SPM, or semi-permeable membranes. These membranes (which protects the cell) only allows certain things to enter the cell.
What process do living organisms break down glucose?
The Glycolysis process allows living organisms break down glucose

Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
Does a permeable membrane will let substances pass through it?
Yes it does permeable membranes are membranes that allows all substances to pass through.

What does serum insulin do?
Insulin allows glucose to move into cells. It thereby maintains glucose homeostasis.
What compound allows materials to move through cell membranes by osmosis?
Water.
The compound that allows materials to move through cell membranes by osmosis is?
water
The process of allows the liver to produce glucose form amino acids when there is adequate glucose in the diet?
gluconeogenesis
Does the presence of integral proteins allows membranes to be selectively permeable to certain molecules?
yes
What is a property of a cell membranes that allows some substances to pass though?
monkey hair
Which type of blood vessel allows for oxygen and carbon dioxide to exchange?
Capillaries are the thin-walled vessels that allow oxygen and carbon dioxide exchange. Their thin walls make it easy for gases to diffuse across the membranes.
