The components of membranes that account for most of their active functions are?
Diverse proteins embedded in the lipid bilayer or positioned at one of its surfaces carry out most of the membranes functions.
Can genes carry hereditary instructions?
Genes carry the instructions to make proteins, i think....
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What role do carrier protiens play in facilitated diffusion?
facilitated diffusion is also called cell-mediated diffusion because a substance transport in this manner diffuses through the membrane using a specific carrier protein to help.first, carrier protein binds to the binding site of the carrier protein ,and then there is a conformational change in the shape of the carrier protein that helps the molecule to diffuse other side of the membrane.
What is energy-carrying molecule called?
carrier molecule1. A molecule that plays a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.2. A lipid-soluble molecule that can bind to lipid-insoluble molecules and transport them across membranes. Carrier molecules have specific sites that interact with the molecules they transport. Several different molecules may compete for transport by the same carrier. See transport protein.

How formaldehyde acts as antiseptic?
Formaldehyde denatures proteins which include the structural proteins, like cell membranes, and the enzymes, which carry out vital biochemical reactions.

Do all chemical substances pass in and out of a cell membrane with equal ease?
no, cell membranes only allow things to pass through it only by using proteins embedded on it for things such as some nutrients and even water. there are two types of these proteins that could be found in the cell membrane, integral proteins, and peripheral proteins. integral proteins are proteins that span throughout the whole cell membrane from one side to another and have polar ends and nonpolar interiors transporting things like nutrients into the cell. peripheral proteins are proteins that only attach to the side of the cell membranes and do not go through it completely. some of these specialized proteins include: aquaporins for transport of water carrier proteins that bind with these necessary molecules to transfer them across the cell membrane glycoproteins that have sugars attached to them channel proteins that allow molecules to freely pass through membrane receptor proteins that bind with proteins on the surface of the cell and enzymatic proteins that help carry out metabolic reactions in the cell
What are the two functions of proteins during cellular transport?
Proteins carry oxygen through the blood, and they also carry electrons throughout the body to enable reactions.
Describe the role of carrier proteins during active transport?
they work as a catalysator for the transportation. They lower the nessesary energy for a transport to start. This can in many cases only be achieved by highly specifically adapted carriers, which in cells is mostly proteins.

What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?
Carrier proteinsProteins in the cell membrane that assist with facilitated diffusion are known as carrier proteins since they carry materials across the membrane. Carrier proteins bind to a molecule on one side of the membrane, change shapes to shield the molecule from the lipid bilayer, and then release the molecule on the other side of the membrane
Does pets go through the scanners at the airports?
You should never put a pet through the x-ray machine. When traveling with a pet in a carry-on carrier, it is best to remove the animal from the carrier, put the empty carrier through the x-ray, while you hand-carry the animal through the metal detector or scanner. Alternatively, you can request that the agents hold the carrier, while you go through the metal detector or body scanner; you can then remove the animal and let them put the empty carrier through the x-ray. In either case, make sure that you have a good grip on your pet at all times--you do not want an escape in a busy airport!
