If a proteins shape is changed it has been?
If a proteins shape is changed it has likely been denatured. This is often a breakdown and rearrangement of the protein.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins
What does a globular protein do in a cell membrane?
Globular proteins act as enzymes and catalyze organic reactions. They also transmit messages to regulate biological processes. Globular Proteins transport molecules through the membrane, and act as regulators within the membrane.
What is the special protein that transport oxygen?
hemoglobin
What type of organic macromolecule is an enzyme?
Many enzymes consist of a protein and a non-protein (called the cofactor). The proteins in enzymes are usually globular. They have tertiary structure and this type of globular protein includes immunoglobins, as well. The structures are held in place by hydrogen bonds, disulfide bridges and ionic bonds.
Which part of the membrane would help a large protein molecule enter the cell?
globular proteins .
Could a protein have what is called a globular shape?
Tritiory proteins are globular proteins. Every enzyme is a globular proteins.
When globular protein has its hydrogen bonds broken it becomes?
Denatured
What does a globular protein become when its hydrogen bonds are broken?
Denatured
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What bonds are disrupted when a protein is denatured?
Peptide bonds that are between proteins are broken when proteins are denatured.
How are molecules such as proteins denatured?
Most commonly a protein can be denatured due to several factors. One of the most common ways of denaturing proteins is through heat. Proteins can also be denatured by exposure to alcohol.
Do denatured proteins have their shape changed?
Denatured proteins do not have any particular shape. A denatured protein is one that has broken amino acid interactions in the secondary and tertiary structures.
What molecules serves as enzymes?
Globular proteins
Are most enzymes globular proteins?
yes
