The oxygen-haemoglobin dissociation curve, also spelled oxygen-hemoglobin dissociation curve, plots the proportion of hemoglobin in its saturated form on the vertical axis against the prevailing oxygen tension on the horizontal axis. The oxyhemoglobin dissociation curve is an important tool for understanding how our blood carries and releases oxygen. Specifically, the oxyhemoglobin dissociation curve relates oxygen saturation (SO2) and partial pressure of oxygen in the blood (PO2), and is determined by what is called "hemoglobin's affinity for oxygen"; that is, how readily hemoglobin acquires and releases oxygen molecules into the fluid that surrounds it. found on wikipedia
What else can I help you with?
How do you calculate the dissociation constant (Kd) from a binding curve?
To calculate the dissociation constant (Kd) from a binding curve, you can determine the concentration of ligand at which half of the binding sites are occupied. This concentration is equal to the Kd value.
Why does an increase in temperature cause the oxygen dissociation curve to shift to the right?
when we excercising, tissue generates heat.those heat would increase the temperature of the neighboring cell, that exercise and need more energy. thus, more oxygen is needed, making the graph shift to the right because hemoglobin release oxygen faster to accord the increasing demand during exercise.
Name two ions that are the products of the dissociation of water?
Another way to describe the dissociation of water is as follows where two water molecules form a hydronium ion (essentially a water molecule with a proton attached) and a hydroxide ion
What is lumbar pelvis dissociation?
Lumbar-pelvic dissociation refers to the independent movement of the lumbar spine (lower back) and the pelvis. This separation of movement is important for functional activities such as walking, running, and bending at the waist. Insufficient lumbar-pelvic dissociation can lead to compensatory movements and potential risk for injury.
When does a J-shaped curve convert to an S-shaped curve?
An "S' curve (on a population chart) reaches its carrying capacity and levels out, while a "J" curve hits its carrying capacity and just continues causing a population explosion and competition for resources.
How do you calculate the dissociation constant (Kd) from a binding curve?
To calculate the dissociation constant (Kd) from a binding curve, you can determine the concentration of ligand at which half of the binding sites are occupied. This concentration is equal to the Kd value.
What are the Causes of right shift of oxygen dissociation curve?
change in pH , temp. carbon dioxide 2,3 BPG shifts the curve
How can one determine the acid dissociation constant (Ka) from a titration curve?
To determine the acid dissociation constant (Ka) from a titration curve, one can identify the equivalence point on the curve where the amount of acid equals the amount of base added. By analyzing the pH at the equivalence point and using the initial concentration of the acid, the Ka can be calculated using the Henderson-Hasselbalch equation.
What is the relationship between metabolic demand and the factors that shift the oxyhemoglobin dissociation curve to the right?

Shift in oxygen-Hb dissociation curve to the right the affinity of hemoglobin for oxygen?
As it shifts to the right, it means that haemoglobin has a lesser affinity for oxygen
Why the Titration curve is varying with different with acid base titration?

The oxyhemoglobin dissociation curve represents a negative feedback mechanism?
A negative feedback mechanism is a system to return a disruption in homeostasis back to homeostasis.A positive feedback mechanism is a system to reinforce or perpetuate a disruption in homeostasis.The oxyhemoglobin dissociation curve represents the Partial pressure in oxygen that will be saturated in the amount of hemoglobin.This curve represents a positive feedback because the binding of Oxygen to hemoglobin facilitates more binding of oxygen to hemoglobin (you can see this in the rapid rise in saturation from 10-40 mm Hg) until it reaches 60 mm Hg where it is somewhat completely saturated
How do you calculate KD from a binding curve?
To calculate the dissociation constant (KD) from a binding curve, you can use the equation KD C50, where C50 is the concentration of the ligand at which half of the binding sites are occupied. This value can be determined by plotting the binding data and finding the point where half of the maximum binding is achieved.
What does the titration curve of H3PO4 reveal about its acid-base properties?
The titration curve of H3PO4 shows that it is a triprotic acid, meaning it can donate three protons (H ions) in a stepwise manner. The curve displays three distinct equivalence points, indicating the presence of three dissociation steps. This reveals that H3PO4 has multiple acidic hydrogen atoms with different strengths of acidity.
Is the dissociation disorder healthy?
Dissociation is a dangerous mental disease.
Is dissociation an endothermic or exothermic process?
Dissociation is an endothermic process.
How can one experimentally determine the value of the dissociation constant (Kd)?
To experimentally determine the dissociation constant (Kd), one can perform a series of experiments where the concentration of a ligand is varied while measuring the binding affinity to a receptor. By plotting the data and analyzing the binding curve, the Kd value can be calculated as the concentration of ligand at which half of the receptor sites are occupied.
