The charge of the iron in haemoglobin for its functioning has to be given. Concept Introduction: Three main types of cells in blood are: Red blood cells or erythrocytes White blood cells or leukocytes Platelets Red blood cells: Also known as erythrocytes and the major function is to transport blood gases. % of erythrocyte is haemoglobin which is the transporter of O 2 and CO 2 Haemoglobin: Composed of four polypeptide chain with a quaternary structure. A central heme molecule is there in each protein chain and each of the four hemes can bind with one O 2 molecule. Each heme molecule in its centre has Fe +2 . The bright red haemoglobin with four oxygens is called oxy haemoglobin. The dark red-purple haemoglobin in which one or more oxygen is lost is called deoxyhaemoglobin.

Three main types of cells in blood are:

Red blood cells or erythrocytes

White blood cells or leukocytes

Platelets

Red blood cells:

Also known as erythrocytes and the major function is to transport blood gases.

% of erythrocyte is haemoglobin which is the transporter of O2 and CO2

Haemoglobin:

Composed of four polypeptide chain with a quaternary structure.

A central heme molecule is there in each protein chain and each of the four hemes can bind with one O2 molecule.

Each heme molecule in its centre has Fe+2.

The bright red haemoglobin with four oxygens is called oxy haemoglobin.

The dark red-purple haemoglobin in which one or more oxygen is lost is called deoxyhaemoglobin.

The urea cycle rids of the body of excess nitrogen by converting it to a form that can be excreted in the urine. Label the steps of the urea cycle shown in the diagram and move the molecules in their positions.

Label each of the intermediates in the urea cycle. H₂N NH₂ NH +H,N A -OOC HN- H H₂N- H₂N= COO NH NH₂ NH H H COO- +H,N COO +H,N COO- +H,N COO- B C D Answer Bank argininosuccinate arginine ornithine citrulline

Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long-chain fatty acids. Many of the symptoms are similar, and include hypoketotic hypoglycemia, low ketone levels and low blood sugar with fasting, and damage to the liver, heart, or muscles due to fatty acid buildup in those tissues. Symptom severity varies with the form of the deficiency. The following abbreviations are used: carnitine acyltransferase (carnitine palmitoyltransferase), CPT and carnitine/acylcarnitine translocase, CACT. Identify each symptom or effect as a deficiency of CPT I, CPT II, or CACT. CPT I deficiency CPT II deficiency CACT deficiency Answer Bank acyl carnitine not transported into mitochondrial matrix acyl carnitine not converted to carnitine in matrix long-chain fatty acids not transferred to carnitine
