Why do the red blood cells carry less oxygen in a smoker?
Red blood cells contain a protein known as haemoglobin (Hb) which is responsible for carrying about 98% of the body's oxygen (the rest is dissolved in the blood). However oxygen is not the only thing that binds to Hb. Both carbon dioxide (CO2) and carbon monoxide (CO) can also bind to it as well (both of which are chemicals produced in cigarette smoke). The binding of CO2 to Hb is normal, and is how the majority of CO2 in the body is trasported to the lungs for exhalation (as it is a bi-product of energy production in the body). However, both CO2 and CO have higher affinities for Hb (i.e. they are more likely to bind to Hb) in the blood, and so when there is more CO and CO2 around, such as when smokers inhale cigarette smoke, the Hb is more likely to bind CO and CO2 than oxygen. CO2 is far more common than CO, and Hb's affinity for it is lower as well. Hb has an incredibly high affinity for CO which explains why it is so toxic to humans as the Hb it binds to is more or less left unusable in the body. This is my understanding of this all at a 2nd year university level of physiology, but I believe it more or less explains everything.
Which of these neurotransmitters does not bind to a plasma membrane receptor?
Nitric oxide does not bind to a plasma membrane receptor.
What is the molecule called that can bind to a receptor protein?
The molecule that can bind to a receptor protein is called a ligand.
What are the structures that allow hormones to bind to their target cells?
Receptors allow hormones to bind to their target cells.
Enhancers must bind to the repressor protein?
That is false because the enhancer must bind to code thesequence
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 happens to rubisco when o2 concentration is much higher then CO2 concentration?
When ther is a higher concentration of O2 than CO2, rubisco can bind O2 in place of CO2.
How many CO2 is found in hemoglobin?
At the end of each protein chain in a hemoglobin (4) there is a amine group for the CO2 to bind to...therefore it can hold 4.
When CO2 mixes with water, ____ is formed. This acid increases ___ ions in the water, which the bind to ____ (used by some marine life to make shells) to form?
When CO2 mixes with water, carbonic acid is formed, the axis then increases positive ions, which then bind with calcium to form calcium carbonate.
What is the problem with burning fossils?
It releases Carbon into the atmosphere, causing it to bind with oxygen to form CO2. An abundance of CO2 causes the earth to heat up unnaturally advancing climate change.
How does carbodioxide moves from bloodstream to lungs?
compare to lungs the pH is more in cells.so that the myoglobin in blood have more affinity towards oxygen,SO THAT OXYGEN IS TRANSFERRED.AND THE CO2 PRODUCED IN THE CELLS WILL BIND WITH HAEMOGLOBIN AND WILL REACH LUNGS.THE INCREASED pH IN CELLS DUE TO THE CO2 WILL BIND WITH H2O PRESENT IN WATER WILL PRODUCE CARBONIC ACID.
Why is the delivery of carbon dioxide to rubisco faster in c4 plants than in c3 plants?
Because c4 plants have greater numbers of oxide tanks than c3 plants! C4 plants also have a special enzyme called Phosphoenolpyruvate carboxylase more commonly known as PEP carboxylase. While rubisco can bind to both CO2 or O2 and thus making the reaction with CO2 go slower, PEP carboxylase only binds with CO2, making the number of reactions with CO2 greater. In a hot area, plants close their stomata to conserve water. This will result in C3 plants running out of CO2 and starting to bind RuBP with O2 in rubisco, which is called photorespiration(does not make glucose). In C4 plants, PEP carboxylase ONLY binds with CO2 and when there still is not a lot of CO2 in the cell, it still can make glucose.
