Six Factors Affecting the Performance of an Enzyme Enzymes are considered catalysts; substances that increase the rates of reactions. Enzymes are responsible for thousands of metabolic processes that involve the sustainment of life‚ one common one is simple food digestion. Without enzymes‚ digestion would occur too slowly for life to continue. Enzymes maintain a protein structure consisting of one or possibly more than one polypeptide chains of defined primary structure‚ and take up a characteristic

List 6 components of the cardiorespiratory system that occur during acute exercise. 1) Heart Rate 2) Stroke Volume 3) Cardiac output 4) Blood Pressure 5) Blood Flow 6) The Blood 2. As heart rate INCREASES or decreases‚ the intensity of exercise INCREASES or decreases. 3. Define maximum heart rate (HRmax). The Highest HR value achieved in an all-out

Lab 9 Report: Exercise Physiology Introduction When the human body is put to work and undergoes any sort of activity‚ it requires more energy and resources in order to sustain this. The cells in muscles and organs must work faster‚ and thus require more energy to do so. The body compensates by increasing heart rate and respiration in order to increase the amount of oxygen entering‚ carbon dioxide leaving‚ and rate at which these gases are delivered to cells throughout the body. In this lab‚ we

Get Some Exercise Workouts for Better Writing Some writers say that writing is like music practice: if you miss a day‚ you’ll notice your work isn’t as smooth; if you miss a couple of days‚ you’ll really notice; and if you miss a week‚ other people will notice. So what can you do when you aren’t actively working on a story‚ novel‚ poem or essay? You can practice. You can exercise. A writing exercise is usually something short that you can complete in an hour or two (or even much less)‚ but which

During Changes in Temperature and pH‚ and Manipulation of Specificity and Cofactors BIOL-1406-SL8 November 16‚ 2012 Abstract Enzymes are biological catalysts. They work by lowering the activation energy needed to initiate a chemical reaction. Enzymes work within an optimal temperature and optimal pH. Enzymes are highly specific for a single substrate. The Enzyme is usually much larger in size than the substrate it binds to. In some cases‚ an enzyme requires something called a cofactor to begin the chemical

Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health. It is performed for many different reasons. These include strengthening muscles and the cardiovascular system‚ honing athletic skills‚ weight loss or maintenance and for enjoyment. Frequent and regular physical exercise boosts the immune system‚ and helps prevent the "diseases of affluence" such as heart disease‚ cardiovascular disease‚ Type 2 diabetes and obesity.[1][2] It also improves mental

There are many other positive benefits that come through the form of exercise. Just as well‚ there are negative effects that can results from lack of exercise. Developing and instilling the importance of exercise through education is valuable to the youth of exercise. When determining physical activity‚ it is important
