What is O2-Hb dissociation curve?
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
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.
Which curve best describes survivorship in marine mollusks?
a Type III curve -The greatest mortality is experienced early on in life, with relatively low rates of death for those surviving this bottleneck. This type of curve is characteristic of species that produce a large number of offspring
Why calculate initial rate of reaction from a curve rather than measure how much gas is released?
Calculating the initial rate of reaction from a reaction curve allows for a precise determination of the reaction rate at the very beginning, providing insights into the mechanism of the reaction. In contrast, measuring how much gas is released over time gives information about the overall extent of the reaction but may not reflect the actual rate at the start due to factors like gas buildup or reaction completion.
How do you calculate the rate of photosynthesis in the hill reaction?
By extrapolating the differential equation, adjacent to the the hypotenuse of the slope, when your results are plotted on the graph. Mathematically it can be worked out using the -b/2a formulae to extrapolate the vertex on the curve which can then beused to calculate the maximum value. This should in the end help to calculate the rate of photosynthesis in the hill reaction. Hope this was helpfull.

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.
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.
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.
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
What are the Causes of right shift of oxygen dissociation curve?
change in pH , temp. carbon dioxide 2,3 BPG shifts the curve
What are the features of binding energy per nucleon curve?
The binding energy per nucleon curve shows how tightly a nucleus is bound together. It typically has a peaked curve with the highest binding energy per nucleon at iron-56. The curve helps us understand the stability and energy released during nuclear reactions.
What is planimeter constant?
The planimeter constant is a value that is used to calculate the area of a closed curve traced by a planimeter. It is a calibration factor specific to the design and operation of the planimeter device being used.
What element has the highest binding energy per nucleon?
Iron has the highest binding energy per nucleon among all the elements. This is because iron's nucleus is the most stable in terms of binding energy per nucleon, making it the peak of the curve on the binding energy curve.
How do you calculate a dissociation constant?
Determination of the Dissociation Constant and Molar Mass for a Weak AcidAbstract: We will determine Ka and the molar mass for an unknown weak acid by using a pH meter to record the pH at intervals during the titration with sodium hydroxide. The titration curve and its first derivative will be plotted to establish the equivalence point. Introduction The strength of an acid is defined by its ability to donate a proton to a base. For many common acids, we can quantify acid strength by expressing it as the equilibrium constant for the reaction in which the acid donates a proton to the standard base, water, as shown in the equations below: HA + H2O Û H3O+ + A-, for H3CCOOH: H3CCOOH + H2O Û H3O+ + H3CCOO - The equilibrium constant for a reaction of this type is called the Acid Dissociation Constant, "Ka", for the acid HA Determination of the Dissociation Constant and Molar Mass for a Weak AcidAbstract: We will determine Ka and the molar mass for an unknown weak acid by using a pH meter to record the pH at intervals during the titration with sodium hydroxide.

Is the velocity constant if a car is going around a curve?
No, the velocity of a car is not constant when it is going around a curve. The direction of the car's velocity is changing as it navigates the curve, even if its speed remains the same, so the velocity is not constant.
