How do substrate concentration and pH affect enzyme-controlled reactions
Dima020 [189]
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.

Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.

In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.

(b) Vaccination against the measles virus will not protect the child against the rubella virus. Why?
vekshin1
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.

The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.

Under normal conditions, what would be the PRIMARY mechanism that his body would use to reduce the amount of PCO2 in the blood
sergeinik [125]

The pH of blood if pco2 drops to 35.0 mmHg is 7.459

The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.

pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )

pK is 6.1 for the bicarbonate buffer system.

HCO3- = 24mm

PCO2  = 35.0 mmhg

pH = 6.1 + log ( 24 / 0.03 * 35.0 )

    = 6.1 + log ( 24 / 1.05 )

    = 6.1 + log 22.8571

    = 6.1 + 1.3590

    = 7.459

Hence, the pH of blood is 7.459
