What is the structure of a protein molecule? After the binding of the G protein-coupled receptor ligand, what molecule does the G protein use for activation? a. guanosine triphosphate b. adenosine triphosphate c. 14-3-3 protein d. connexin e. None of the answers are correct. What p...
How does a protein catalyze a reaction?However, catalysts are also found in nature in the form of enzymes. Enzymes are proteins that are able to lower the activation energy for various biochemical reactions. They do this by binding the reactant(s), known as the substrate(s), to an active...
What does the nucleus do in protein synthesis? What molecule holds instructions for the synthesis of proteins? Proteins are made during the process of What are the monomer "building blocks" that make up proteins? Ribosomes are made out of which macromolecule?
A tripeptide is a specific type ofpeptide, or protein molecule, that is formed when three differentamino acidsjoin together. Each of these molecules contains three amino acids and threepeptide bonds. There are many different variations, and accordingly many different jobs and functions; in general,...
A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment. Each transport protein is specific to a certian molecule (indicated by matching colors). © 2010 Nature ...
The "Molecule Cloud View" module allows you to visualize a group of molecules as their respective van der Waals surfaces within 3D datasets, specifying their positions and orientations. To use this feature, you need a molecule template, such as one from the Protein Data ...
To successfully catalyze an inflammatory reaction and achieve naïve cell activation and expansion, three binding signals must occur at the same time: TCR binding, cytokine signaling, and the binding of a co-stimulatory molecule, such as CD28. Cytokines and co-stimulatory molecules bolster the ef...
is because dextrose only has one molecule, so there’s no chain for the body to break down. Longer chain molecules, such as proteins, take longer to be broken down by the body and as a result, don’t cause the blood sugar to spike in the way that single molecules like dextrose do....
What does DNA polymerase make? What type of bond connects two complementary nucleotides? What type of biological molecule is DNA helicase? What type of organic compound is DNA? What does a DNA-binding protein do? What type of DNA supercoiling is the most common?
