Name tags of cells giving each an identity?
The name tags of cells giving each an identity are marker proteins. Proteins that transmit information into the cell by reacting to certain other molecules are receptor proteins.
How are passive and active transport the same?
They both transport proteins and molecules across the cell membrance. Each have 3 different types within themselves. There aren't very many similarities. They function in different ways.
Proteins are what?
Proteins are macromolecules that are made and used by all living things, relatively big molecules (polymers) that consist of smaller building blocks (monomers) called amino acids. Each amino acid is a chemical composed of carbon, nitrogen, hydrogen, and oxygen and some of them have other elements like sulfur. These amino acids bond to each other by a bond called the peptide bond. After the linear protein molecule forms it folds into a 3D structure producing the active protein. In some cases several folded protein molecules stick together (and sometimes with other nonprotein molecules, e.g. heme units in the case of hemoglobin to carry oxygen in the blood) forming a complex that can do more than the individual proteins can do alone. Proteins of differing types perform most active functional and structural roles in both living cells and in viruses.
How does Cohesion cause water to stick together?
cohesion is when molecules of a certain similar kind (in this case water molecules) are more attracted to each other than to those of other substances. Water molecules are strongly cohesive as each molecule may make four hydrogen bonds to other water molecules.
Substances inside the plasma membrane are?
Plasma membrane in made up of phospholipid bilayer and proteins. It has a hydrophobic tail facin each other on the bilayer, and polar head that face outside to the polar environment. Proteins such as integral and peripheral proteins are presenting on the membarane.
The smaller unit molecules which combine to form proteins and polypeptides are called what?
The smaller unit molecules which combine to form proteins and polypeptides are called amino acids. The amino acids are joined to each other by peptide bonds.
Which group contains molecules that are each assembled from smaller organic compounds?
3: proteins, DNA, fats, starch
Which group only contains molecules that are each assembled from smaller organic compounds?
3: proteins, DNA, fats, starch
What is Cell recognition proteins are?
Cell recognition proteins allow cells to recognize each other as well as other molecules.
What is cell recognition proteins?
Cell recognition proteins allow cells to recognize each other as well as other molecules.
Why water dissloves so many different substances?
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
What is the building block each of each of the four classes of organic molecules?
proteins,carbohydrates,lipids,and nucleic acids
How are new substances formed during chemical reactions?
Chemical bonds in the starting substances must break. molecules are always moving. if the molecules bump into each other with a enough energy, the chemical bonds in the molecules can break. the atoms then rearrange, and new bonds form to make new substances.
Name tags of cells giving each an identity?
The name tags of cells giving each an identity are marker proteins. Proteins that transmit information into the cell by reacting to certain other molecules are receptor proteins.

What does each gene have instructions for?
Genes, which are made up of DNA, act as instructions to make molecules called proteins.
What does each gene have instructions for makeing?
Genes, which are made up of DNA, act as instructions to make molecules called proteins.
