The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
Answer:
In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
Explanation:
Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
Answer: Red blood cell count is a diagnostic blood test used to determine the amount of red blood cells an individual has.
Percentage of reticulocytes refers to the amount of immature red blood cells one has.
Hemoglobin is the protein component of red blood cells responsible for carrying oxygen.
Hematocrit is the proportion of red blood cells in the total volume of blood.
Mean corpuscular volume refers to the mean volume of red cells within an organism.
Mean corpuscular hemoglobin concentration refers the intracellular hemoglobin count.
Explanation: Anemia is a condition that is characterized by a reduced total hemoglobin count or number of red blood cells. Anemia can be classified according to various factors that include pathophysiology, that is the factors surrounding the onset of the condition or by cell size, which refers to mean corpuscular volume (MCV) or by the amount hemoglobin, which is referred to as the mean corpuscular hemoglobin (MCH). The diagnosis of anemia is dependent on red blood cell counts which encompass reticulocyte, platelets and leukocyte counts. Critical blood counts that look at MCV and MCH are a disgnostic feature for the various types of the condition. A high reticulocytes percentage is often associated with anemia.
