The bonds between carbon and hydrogen are broken down with the help of oxygen to give energy (oxidation). Carbohydrates produce 4.1kcal/g energy under laboratory conditions. This is called calorific value . However, in the body they produce 4kcal/g of energy. This is called physiological fuel va..

i) The pelvic girdles join to form bowl like structure and the wide space enclosed between them forms the pelvis which support and protect the abdominal organs. ii) The pelvic girdles of female are more flexible, broader and shallower than those of male, this is an adaptation for pregnancy and par..

i. They protect the heart, large blood vessels and lungs. ii. They bear respiratory muscles, and play an important role in respiration. iii. The last two pairs of ribs protect the kidney..

It is a component of nucleic acid, phospholipids, ATP, nucleoprotein, NAD, NADP and a number of co-enzymes. Since the young cells are the seat of maximum metabolic activities, maximum phosphorus is found in the meristems, fruits and seed..

1. Is a component of chlorophyll and magnesium pectate. 2. Essential for the formation of carotenoids. 3. Required by a large number of enzymes connected with phosphate transfer. 4. For binding of ribosomes. 5. Higher concentrations of Mg 2 + ions are found in seeds and growing areas of root and st..

1. Iron is a constituent of cytochromes, ferredoxin, nitrogenase, catalase peroxidase, hematin etc. 2. Essential for the development of chloroplast and chlorophyll. 3. Many of iron containing enzymes take part in electron transfer in both photosynthesis and respiration. 4. Structure of polyribosome..

1. Constituent of carbonic anhydrase - zinc is essential for supply of CO 2 to the chloroplast and for the evolution of CO 2 during respiration. 2. Production of IAA (auxi..

1. It can take part in electron transport system in both respiration and photosynthesis. 2. In photosynthesis the copper containing enzyme is plastocyanin. 3. It is the connecting link between photo system - I and ..

Its precise role is not well known. i) However, with Na + and K + , it helps in determining solute concentration and anion - cation balance in the cells. ii) Chlorine plays an important role in photosynthesis. It takes part in the water splitting reaction, thus releasing oxyg..

It stores the nitrogenous wastes of the embryo, so it acts as an extra embryonic kidney. In eutherian mammals it takes part in placenta formati..
