What else can I help you with?
Is a glycoprotein a type of peripheral protein that can be used as a receptor or in enzymatic functions?
it binds with several signaling molecules as it has shape that is complementary to signaling molecules.
What types of bonds are apt to be more common in the nonaqueous interior environment of a protein than in the aqueous surface environment of a protein?
Hydrophobic interactions and disulfide bonds are more common in the nonaqueous interior of a protein due to the absence of water molecules that would disrupt these interactions. In contrast, hydrogen bonds and ion-pair interactions are more prevalent on the aqueous surface of a protein where water molecules can mediate these interactions.
Who discovered stomata?
Stomata were first observed by the Italian biologist Marcello Malpighi in the 17th century. He used a microscope to study plant tissues and discovered these small pores on the surface of leaves.
What role does the ribosome?
The ribosome is responsible for protein synthesis in a cell. It reads the mRNA code and translates it into a specific sequence of amino acids to build the protein. Ribosomes are composed of proteins and ribosomal RNA (rRNA) molecules.
What is the flat surface of a microscope that holds the slide for viewing called?
The flat surface of a microscope that holds the slide for viewing is called the stage. It is where the specimen slide is placed for examination under the microscope's lens.
What would a biologist use to study the protein molecules on the surface of a cell?
a scanning electron microscope
Would a biologist who is studying the details of protein molecules on the surface of a cell would they most likely use a?
A biologist studying protein molecules on the surface of a cell would likely use tools such as microscopy, protein purification techniques, and bioinformatics software to analyze and characterize the proteins. They may also use techniques like Western blotting, immunofluorescence, and flow cytometry to study protein expression and localization.
What type of microscope allowed scentists to view molecules?
A scanning probe microscope can provide a three-dimensional image of atoms or molecules on the surface of an object.
An enzyme is a protein with a pocket on its surface called an?
An enzyme is a protein with a pocket on its surface called an active site. This is where the binding of substrate molecules take place and where chemical reaction happens.
What instrument used to take pictures of atoms and molecules within a substance?
A scanning tunneling microscope (STM) or an atomic force microscope (AFM) is typically used to capture images of atoms and molecules within a substance. These instruments use a sharp tip to scan the surface of a sample at the atomic level, allowing for visualization of individual atoms and molecules.
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
What does a scanning tunneling microscope allow scientists to see?
A scanning tunneling microscope allows scientists to see individual atoms and molecules on a surface by measuring the electrical current that flows between the microscope's probe tip and the sample surface. This technology provides high-resolution imaging of surface structures, enabling the visualization of atomic-scale details.
On Surface Dr Laura Daughtery is?
A marine biologist
A protein on the surface of HIV can attach to what proteins on the surface of healthy human cells?
HIV's surface protein, gp120, can attach to CD4 receptors on healthy human cells. This interaction allows HIV to enter and infect the cell by binding to the CCR5 or CXCR4 co-receptors on the cell surface.
Is a glycoprotein a type of peripheral protein that can be used as a receptor or in enzymatic functions?
it binds with several signaling molecules as it has shape that is complementary to signaling molecules.
Principle of salting out method for genomic DNA isolation?
Th There are hydrophobic amino acids and hydrophilic amino acids in protein molecules. After protein folding in aqueous solution, hydrophobic amino acids usually form protected hydrophobic areas while hydrophilic amino acids interact with the molecules of solvation and allow proteins to form hydrogen bonds with the surrounding water molecules. If enough of the protein surface is hydrophilic, the protein can be dissolved in water. When the salt concentration is increased, some of the water molecules are attracted by the salt ions, which decreases the number of water molecules available to interact with the charged part of the protein. As a result of the increased demand for solvent molecules, the protein-protein interactions are stronger than the solvent-solute interactions; the protein molecules coagulate by forming hydrophobic interactions with each other. This process is known as salting out. ere are hydrophobic amino acids and hydrophilic amino acids in protein molecules.

Are surface protein receptors protein?
Yes, surface receptors are made of protein units in cells.
