Explain why it would not be possible to accurately measure hemoglobin concentration if the RBCs were not first lysed.
docker41 [41]

Because hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

<h3>Measure of hemoglobin concentration</h3>

Hemoglobin is a complex found in blood which is responsible for transporting oxygen to cells of the body.

Hemoglobin is composed of heme and the proteins alpha and beta globin.

Hemoglobin is found within the cytoplasm of red blood cells.

Since hemoglobin is compartmentalized inside the RBCs, lysis of RBCs is necessary for accurate measurement of hemoglobin levels.

2. If a cell has a very large amount of ribosomes attached to its rough
Otrada [13]

Answer:

Protein

Explanation

Ribosome and Rough E.R are organelles  in the cell.

E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system  called the reticulum.

Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.

They are small in number and are made up of RNA and protein.Generally the protein  synthesised  in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies
