No, carbon dioxide (CO2) binds to a different site on hemoglobin than oxygen (O2). CO2 primarily binds to the amino groups of the protein portion of hemoglobin, forming carbaminohemoglobin. This is an important way that CO2 is transported in the blood.

What is the site of oxygen binding on hemoglobin?
You have Iron atoms in hemoglobin. This atom is the binding site for oxygen in case of hemoglobin.
Does carbon monoxide compete with oxygen for the same binding site?
Yes, carbon monoxide competes with oxygen to bind to hemoglobin in the blood. Carbon monoxide has a much higher affinity for hemoglobin than oxygen, which can lead to carbon monoxide poisoning as it prevents oxygen from binding.
What binding site does carbon monoxide has?
Carbon monoxide has a high affinity for the heme group in hemoglobin, binding to the iron atom in place of oxygen. This prevents oxygen from binding, reducing the blood's ability to transport oxygen to tissues, leading to tissue hypoxia.
What inhibitor has a structure similar to the substrate?
Competitive inhibitors have a structure similar to the substrate, allowing them to bind to the active site of the enzyme and block the substrate from binding. This competition for the active site reduces the enzyme's catalytic activity by preventing the substrate from binding and undergoing a reaction.
What are active and binding sites of proteins?
The active site of a protein is the specific location where substrate molecules bind and undergo a chemical reaction. It typically contains amino acid residues that contribute to catalyzing the reaction. The binding site is a broader term that refers to any region on the protein where molecules can bind, not only for catalysis but also for other functions such as regulatory interactions.
What is the site of oxygen binding on hemoglobin?
You have Iron atoms in hemoglobin. This atom is the binding site for oxygen in case of hemoglobin.
What portion of hemoglobin molecule binds oxygen?
Hemoglobin contains a heme group with an Iron ion attached to it. The iron is what binds to O2.
Does CO2 bind at the same site on the hemoglobin molecule as O2 If not where does CO2 bind?
No. Carbon monoxide binds to the same site as oxygen, i.e. the central iron. Carbon dioxide binds to the globin molecule.
What is the region on an enzyme to which a substrate bind is called?
Binding site.
Where is the binding site for oxygen in the body?
Hemoglobin on red blood cells.
How are the different types of inhibitors different?
Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding. Noncompetitive inhibitors bind to a site other than the active site, changing the shape of the enzyme and preventing substrate binding. Uncompetitive inhibitors bind only to the enzyme-substrate complex, preventing catalysis.
Does carbon monoxide compete with oxygen for the same binding site?
Yes, carbon monoxide competes with oxygen to bind to hemoglobin in the blood. Carbon monoxide has a much higher affinity for hemoglobin than oxygen, which can lead to carbon monoxide poisoning as it prevents oxygen from binding.
What requires a binding site called palindrome?
DNA polymerase requires a binding site called palindrome. This binding site allows the enzyme to recognize and bind to specific sequences on the DNA strand in a complementary manner, ensuring accurate copying of genetic information during DNA replication. Palindromic sequences are characterized by their two-fold symmetry, which aids in DNA polymerase's ability to bind and initiate replication.
What is the difference between an allosteric enzyme and a non-allosteric enzyme?
An allosteric enzyme has multiple binding sites that can be used to modulate its activity through the binding of effectors or ligands, whereas a non-allosteric enzyme typically only has one active site. Allosteric enzymes can exhibit cooperativity, meaning that binding at one site affects binding at another site, while non-allosteric enzymes do not show this behavior.
Is substrate bind to the enzyme by collision?
Collision only introduces the substrate to the active site. Binding is usually hydrogen bonding.
One binding site on a ribosome holds an mRNA molecule and the other two binding?
sites hold tRNA molecules. The mRNA binding site is where the mRNA molecule binds and is read during translation. The tRNA binding sites are where tRNAs carrying amino acids bind and deliver them to the growing polypeptide chain.
Chemical of similar shape to the substrate that can bind in the active site without product being formed?
A competitive inhibitor is a chemical that has a similar shape to the substrate and can bind to the active site of the enzyme without the product being formed. This binding prevents the substrate from binding to the enzyme and forming the product, reducing the enzyme's activity.
