Document Summary

A protein found in red blood cells, __________, is necessary for the transport of oxygen from the lungs to the cells of the body. You correctly answered: there is inadequate hemoglobin in the red blood cells, and insu cient oxygen is carried in the blood. Predict question: how will the hemoglobin levels for the female olympic athlete (sample 5) compare with the hemoglobin levels for the healthy female (sample 2)? https://media. pearsoncmg. com/bc/bc_0media_ap/physioex/10/ex11/act3/ i. Your answer: the hemoglobin levels for the female olympic athlete will be greater than those for the healthy female. You correctly answered: higher testosterone levels in males promotes more rbc production. Blood sample gm hb per 100 ml blood. You scored 100% by answering 3 out of 3 questions correctly. To determine the amount of hemoglobin in a blood sample. You correctly answered: all of these answers are correct. Which of the following diseases is known to increase hemoglobin levels in an individual? https://media. pearsoncmg. com/bc/bc_0media_ap/physioex/10/ex11/act3/ i.

You have been asked to estimate the content of hemoglobin in a test sample. You decide to perform an assay where the concentration of hemoglobin in the test sample can be measured and compare with a hemoglobin standard curve whose range is across 25 to 800 ug/well. The test sample is treated identically (volume assayed is 10 ul) to the standard hemoglobin and gives an absorbance reading of 0.4. By using the kaleidagraph program to analyse the data, the following equation is produced: y = 0.0005 + 0.0018x Using the above information, answer the following questions:

a) what is the amount of hemoglobin in the test sample added to the well expressed in ug?

b) what is the concentration of the hemoglobin in the test sample expressed in g/L?

c) If the red blood cell count expressed as number of cells/L is 5.5 x 1012, what would be the amount of hemoglobin per red blood cell in the test sample? Express the results in picograms/cell.

Which of the following is false?

a. The release of oxygen from the R form of hemoglobin in red blood cells is more pronounced than in pure hemoglobin as the concentration of oxygen decreases.

b. In the presence of 2,3-bisphosphoglycerate, the affinity for oxygen in fetal hemoglobin is higher than maternal hemoglobin

c. Myoglobin does not use an allosteric effect

d. Hydrogen ions and carbon dioxide will help increase the release of oxygen from the R form of hemoglobin in the tissue.

e. None of the above

The main role of the protein hemoglobin is to transport oxygen. Red blood cells use hemoglobin to pick up oxygen from the lungs and then drop it off at subsequent cells. Blood also carries sugar (glucose) around the body. Glucose is picked up in the intestine and dropped off subsequent cells. When an individual has sickle cell anemia, blood does not flow properly and oxygen and sugar are not transported effectively.

Oxygen is picked up in the lungs. The cells of lung tissue are held together with junctions. Which of the following is likely to mediate this junction if liquid cannot pass between the cells in the extra-cellular matrix or directly from cell to cell?

		Cadherin
		Connexin
		Calnexin
		Claudin
