Oxygen cooperativity Study guides, Class notes & Summaries

You're using anion exchange chromatography to purify a small globular protein. After passing the mixture through the column, you find that your protein did not "stick" to the resin and flowed right through. What is a plausible reason for this to have occurred? Correct Answer-The pH of the solution is close to the isoelectric point. Oxygen binding that affects the cooperatively of hemoglobin is an example of heterotrophic regulation. Correct Answer-False You have determined that a leucin...

Ligand correct answers A molecule which is reversibly bound by a protein; A small molecule that binds specifically to a larger one; for example, a hormone is the ligand for its specific protein ligand. Induced Fit correct answers Proteins or enzymes may undergo conformational changes when a lignand binds which alters the function of the protein; What do Myoglobin and haemoglobin contain? correct answers They contain a hem prosthetic group which binds oxygen. What does Heme consist of? c...

WGU C624 Biochemistry Module 3, Exam Questions and answers, 100% Accurate. VERIFIED. Describe the functions of hemoglobin and myoglobin. - -Hemoglobin transports oxygen, Myoglobin stores oxygen. The correct number of subunits, heme groups, iron and oxygen that bind to hemoglobin versus myoglobin. - -Hemoglobin has: 4 subunits 4 heme groups 4 iron molecules binds 4 molecules of oxygen. Myoglobin has: 1 subunit 1 heme group 1 iron molecule binds 1 molecule of oxygen. Cooperat...

AQA AS Biology - Mass Transport 3.3.4 Questions & Answers 2024 What is the structure of haemoglobin? - ANS-A quaternary structure with 4 polypeptide chains (2 alpha, 2 beta) Each chain associated to a haem group containing an Fe2+ ion Each Fe2+ can carry one oxygen - hence Hb can carry a maximum of 4 oxygen What is the role of haemoglobin? - ANS-Transport oxygen around the body How does haemoglobin transport oxygen? - ANS-When ppO2 is high - at lungs - Hb has a high affinity for oxyge...
