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.
Answer: It is important in forming complicated molecules because of it's atomic structure.
Answer:
4. Monomers
Explanation:
Monomers are small and simpler substances that are bonded together to form large and complex polymers. Many amino acids are bonded by a peptide linkage to form complex polypeptides. Here, amino acids are the monomers while the polypeptides are the polymers. Glucose molecules are bonded by a glycosidic linkage to form cellulose or starch or glycogen. Here, glucose is a monomer while cellulose, starch, and glycogen are the polymers. Therefore, macromolecules are made up of monomers.
Answer:
Answer:
15 grams of alcohol is circulating in his blood
Explanation:
BAC (Blood alcohol content) is defined as the certain level of alcohol in the blood stream.
Given,
BAC of an adult male = 0.30 = 0.30 g/100 ml
Total blood volume = 5 L = 5000 ml
Mass of alcohol in 5000 ml of blood:
= 0.30 g/100 ml × 5000ml
= 15g
Therefore,
15 grams of alcohol is circulating in his blood
