Explanation:
Deliver nutrients to the body cells.
Answer:
The statements are correct.
Explanation:
Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.
Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.
Answer:
D
Explanation:
Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.
In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)
Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.
Answer:
c. increase blood pH.
d. interfere with oxygen binding to hemoglobin.
Explanation:
A inhibitor of carbonic anhydrase increases the pH of the blood due to prevent the production of carbonic acid from the carbon dioxide formed during cellular respiration. This carbonic acid decreases the pH of the blood so inhibitor of carbonic anhydrase is responsible for the increase in the pH. It also interfere with oxygen binding to hemoglobin because oxygen bind with hemoglobin in low pH but the pH is higher due to inhibitor of carbonic anhydrase.
