When a person is exercising the body needs to deliver increased amounts of oxygen to the muscles. Which componentes f the blood
ad-work [718]

In human blood, there is a compound inside the RBCs called haemoglobin which ensures that the muscle will receive enough oxygen during exercise.

<h3><u>Explanation:</u></h3>

In human blood, the red blood corpuscles contain the haemoglobin. Haemoglobin is a iron chelated compound containing porphyrin ring and a globin tail which can establish co-ordinate covalent bond with both oxygen and carbon dioxide. The bonding element depends on the concentration of these two gases. In lungs, where the oxygen concentration is more than carbon dioxide, the haemoglobin bonds with oxygen and brings it to the tissues where carbon dioxide concentration is more. This makes the haemoglobin to release oxygen and bond with carbon dioxide which is brought back to lungs. This is the process by which each and every tissue including the muscles recieve oxygen.

In muscles there is Myoglobin which is another iron-porphyrin compound which has several times more affinity for oxygen than haemoglobin. This helps to extract more oxygen from haemoglobin in muscles.

Which of the following statements about the smooth endoplasmic reticulum is/are correct?
olya-2409 [2.1K]

The correct answers are:

• Liver cells are abundant in SER.  

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.  

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
