Introduction:
Respiration can be defined as the process of intake of oxygen into the cells and tissues of the body along with the release of carbon dioxide and energy. The carbon dioxide released during the process of
Answer to Problem 1SQ
Correct answer:
Respiratory proteins such as hemoglobin contain metal ions and increase the efficiency of oxygen transport. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
Option d. is given as “both a and c.”
Hemoglobin is an example of a respiratory protein. Respiratory proteins are referred to those proteins that help in enhancing the blood capacity for the transport and delivery of oxygen. Hemoglobin is the respiratory protein that consists of one or more than one metal ions. Hemoglobin increases the efficiency of oxygen transport.
Reason for incorrect answer:
Option a. is given as, “contains metal ions.”
Hemoglobin contains metal ions. However, it also increases the efficiency of oxygen transport. Hence, option a. is incorrect.
Option b. is given as, “occur only in vertebrates.”
The hemoglobin is a respiratory protein that is present in all vertebrates along with some invertebrates. Hence, option b. is incorrect.
Option c. is given as, “increase the efficiency of oxygen transport.”
Respiratory proteins are responsible for enhancing the blood capacity for the transport and delivery of oxygen. However, hemoglobin also contains metal ions. Hence, option c. is incorrect.
Hence, the options a., b., and c. are incorrect.
Hemoglobin consists of metal ions and increase the efficiency of oxygen transport. Thus, the correct option is d.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place.

Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables.
