What type of membrane proteins allow cells to identify one another?
Receptor proteins.
Which type of proteins are involved in nutrient transport and why?
integral proteins, because they span the membrane and thereby are able to carry nutrients across the membrane
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What type of bilomolecuels make up a cell membrane bi layer?
phospholipids and proteins
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
What type of protein controls what goes in and out of cells?
Integral Membrane Proteins control the movement of substances into and out of the Cell (that cannot pass directly through the bi-lipid layer). These are proteins that span the width of the membrane [40 nanometers], and can be channels, pumps, gates of many descriptions, co-transporters, etc. As proteins go, these trans-membrane proteins have internal and external hydrophyllic lengths that have immensely important and varied bio-functions, and the trans-membrane segment is of course hydrophobic.
What do the channel proteins in the cell membrane do?
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
What type of proteins go in and out of cells?
membrane
What type of membrane proteins allow cells to identify one another?
Receptor proteins.
Which type of proteins are involved in nutrient transport and why?
integral proteins, because they span the membrane and thereby are able to carry nutrients across the membrane
Which type of membrane protein attaches to specific hormones such as insulin?
The membrane proteins that attach to specific hormones such as insulin are called receptor proteins.
What type of proteins speed up a chemical reaction?
Enzymes are proteins which speed up chemical reactions.
What type of proteins regulates nearly all chemical reactions in cells?
enzyme
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Which of the following incorrectly matches the type of cell type of protein and site of the proteins synthesis?
prokaryote, plasma membrane protein, ribosome bound to plasma membrane
What type of bilomolecuels make up a cell membrane bi layer?
phospholipids and proteins
What enzyme can be found in membrane?
Enzymes are like complex biological catalysts (matter of fact, that's exactly what they are..). They help your body break down certain proteins, vitamins, and other molecules. People who are lactose intolerant lack an enzyme to process lactose (a complex sugar in most milk). They must either drink lactose-free milk, or take certain supplements that introduce lactose enzymes into the body.
