15. Explain how oxygen and carbon dioxide are carried through the blood.
How the oxygen is carried through the blood is in the lungs of the oxygen diffuses from the respiratory membrane transport into the blood. About 98. 5% oxygen is carried in the blood connecting with the iron- containing that combines heme groups is known for oxyhemoglobin. It has four oxygen from fully saturated oxyhemoglobin that has oxygen molecules attached. The oxygen is transported by blood to ensure us to know which is essential to live. The carbon dioxide is more common in the blood that oxygen. It is transported in three sections. The first one has 7% is carried over to the carbon dioxide.
16. List and describe the function of two enzymes necessary for the breakdown of each of the following: Lipids, proteins, and carbohydrates.
The proteins digestion is in the stomach. Duodenum goes in the action of three main enzymes secreted by the mouth, pepsin, and trypsin and chymotrypsin. Also the enzymes breakdown some food proteins becoming into polypeptides. That is broken down by few dipeptides and exopeptidases that goes into the amino acids. The carbohydrates combines of starches, sucrose, lactose milk,…show more content… List two male dominant and two female dominant hormones and give their specific functions. The two male dominant hormones is testosterone and luteinizing hormone. The testosterone is a male hormone of the reproduction and part of the bone and muscle to keep its strength. It’s produced by the gonads and it’s an androgen. It also stimulates the growing of the male characteristics. It works with the development of the male which is internal and external reproductive organs that connects the production of the sperm in male adults. Testosterone shows signals that the body needs to create new blood cells and changes in puberty to increase the growth in males. Another hormone in males is luteinizing hormone is an act to receptors on leydig cells of the
