Questions Related to components of blood

Which of the following components are present in the plasma?

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Water

  2. Salt

  3. Proteins

  4. All of the above

Show answer
Correct Option: D
Explanation:

One half of blood is composed of red blood cells, white blood cells and platelets which are considered as solid part of blood and another half is composed of water, salts and proteins which is the fluid part of blood. The fluid part of blood is known as plasma. Hence the components present in the plasma are water, salts and proteins.

So, the correct answer is 'All of the above'.

The matrix of the plasma contains

  1. Water and Salts

  2. Blood cells

  3. Only platelets

  4. Only RBCs and WBCs

Show answer
Correct Option: A
Explanation:

Plasma is the extracellular matrix which holds the blood cells. It makes 55 percent of the total blood volume. It consists of 95% of water and 8% of proteins. The protein like serum albumins, globulins, fibrinogen etc. In addition, it also contains glucose, electrolytes and clotting factors. Thus, the correct answer is option A.

Percentage of protein is more in

  1. Lymph

  2. Blood

  3. Plasma

  4. W.B.C

Correct Option: B

Blood proteins connected with antibodies are

  1. Albumins

  2. $\beta$-globulins

  3. Gamma globulins

  4. $\alpha$-globulins

Show answer
Correct Option: C
Explanation:
One half of blood is composed of water, salts, and proteins which is the fluid part of blood. The fluid part of blood is known as Plasma. Plasma is a straw-colored, viscous fluid it has about 90-92% water and 6-8% proteins.  Fibrinogen, globulins, and albumins are the major proteins present in plasma. Hence Globulin is a plasma protein. Globulins are of three types alpha, beta, and gamma. Gamma globulins are blood proteins connected with antibodies.
So, the correct answer is 'Gamma globulins'.

Most of the blood proteins are 

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Acidic

  2. Basic

  3. Neutral

  4. All the above in equal proportions

Show answer
Correct Option: A
Explanation:

Plasma is composed of 90-92% water and 6-8 % plasma proteins. Fibrinogen, globulins and albumins are the major proteins. The pH of blood is 7.35 to 7.45 slightly alkaline. Most of the blood proteins are acidic in order to neutralize the pH of blood.

So, the correct answer is 'Acidic'.

About $97\%$ of oxygen is transported by RBC. The remaining $3\%$ is?

  1. Retained in lungs

  2. Dissolved in plasma and transported

  3. Attached to cell membrane

  4. Inside mitochondria

  5. In peroxisomes

Show answer
Correct Option: B

The amount of water present in blood plasma is

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. 60%

  2. 70%

  3. 80%

  4. 90%

Show answer
Correct Option: D
Explanation:
One half of blood is composed of red blood cells, white blood cells and platelets which are considered as solid part of blood and another half is composed of water, salts, and proteins which is the fluid part of blood. The fluid part of blood is known as Plasma. Plasma is a straw-colored, viscous fluid it has about 90-92% water and 6-8% proteins. Hence The amount of water present in blood plasma is 90%.
So, the correct answer is '90%'.

Blood does not contain

biology simple nutrients into cells blood and its components components of blood composition of blood

  1. Calcium.

  2. Prothrombin.

  3. Fibrinogen.

  4. Elastin.

Show answer
Correct Option: D
Explanation:

Elastin is a highly elastic protein found in certain connective tissues throughout the body. It is mostly found in the extracellular matrix of the skin and internal organs of the body. Calcium, prothrombin, and fibrinogen are the blood clotting factors present in the blood. Blood is a fluid connective tissue it does not require elasticity hence elastin is absent in blood.

So, the correct answer is 'Elastin'.

The major proteins of blood plasma are

  1. Albumin, globulin and fibrinogen.

  2. Collagen, elastin and fibrinogen.

  3. Albumin, glutelin and p-protein.

  4. Actin, myosin and tubulin.

Show answer
Correct Option: A
Explanation:
One half of blood is composed of red blood cells, white blood cells and platelets which are considered as solid part of blood and another half is composed of water, salts, and proteins which is the fluid part of blood. The fluid part of blood is known as Plasma. Plasma is a straw-colored, viscous fluid it has about 90-92% water and 6-8% proteins. The major proteins of blood plasma are Albumin, globulin, and fibrinogen.
So, the correct answer is 'Albumin, globulin, and fibrinogen'.
