What does electronegativity allow water to do?
The higher electronegativity of oxygen allows water to carry partial charges (negative on oxygen, positive on hydrogen). These partial charges allow water to bind strongly with itself, and allows it to interact with polar molecules. The partial charge allows polar molecules to dissolve in water.
How does hplc works?
HPLC works when a reservoir holds the solvent and then it is sent to the pump manager.Next it goes to the HPLC coloumn .After it goes through there it usually ends in the detector than waste. Generally the stationary phase in the HPLC column is made up of alkyl coated silica making it relatively non-polar. Due to this the technique is also called reversed-phase HPLC.
Proteins that attach molecules in order to deliver them to another site?
These proteins are likely transport proteins, such as carrier proteins or channel proteins, which bind to specific molecules and facilitate their movement across cell membranes or through the bloodstream. These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
How many oxygen molecules bind to myoglobin?
1 Each myoglobin molecule has one heme group and can bind one oxygen molecule. Hemoglobin on the other hand can bind up to 4 molecules of oxygen.
What binds to receptor molecules on the host cell membrane?
Ligands bind to receptor molecules on the host cell membrane. These ligands can be hormones, neurotransmitters, or other signaling molecules that trigger a cellular response when they bind to their specific receptors.
What bond does hydrogen and hydrogen form?
Two atoms bind with non polar covalent bond.Hydrogen molecules have London Forces among them.
How does facilitated diffusion occur through a protein channel?
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
Which of these extracellular signal molecules could diffuse through a plasma membrane and bind to an intracellular receptor?
Small hydrophobic molecules like steroid hormones can diffuse through the plasma membrane and bind to intracellular receptors, which then translocate into the nucleus to regulate gene expression.
What does electronegativity allow water to do?
The higher electronegativity of oxygen allows water to carry partial charges (negative on oxygen, positive on hydrogen). These partial charges allow water to bind strongly with itself, and allows it to interact with polar molecules. The partial charge allows polar molecules to dissolve in water.
Why do polar covalent molecules have higher melting points than non polar covalent compounds?
They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.
What small molecules bind to hemoglobin?
Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.

What do signal molecules bind to in cells?
Receptor Proteins
What membrane surface molecules bind to proteins and serve as molecules identification tags?
Carbohydrates

Why do some substances have no odor scientifically?
Small, non-polar molecules do not bind to your olfactory receptors because they have no partial charges.
