how VO²max affects performance?” VO2 max is the highest rate at which oxygen can be taken up and utilized during exercise by a person. For optimal performance‚ the working muscles need a constant supply of oxygen to provide energy or ATP (Adenosine triphosphate) to initiate movement. Maximal oxygen intake can have significant effects on an individual’s performance. The amount of oxygen the muscles receive impacts upon one’s performance. Take two athletes for example; the first athlete has a higher

owerPower‚ Sex‚ Suicide Mark Leung Mr. Behrend SCH3U0-01 Tuesday‚ October 25‚ 2011 Nick Lane‚ the author‚ has a very big interest in the mitochondria. The book gives very detailed descriptions about the mitochondria and biological terms regarding about the mitochondria. The title “Power‚ Sex‚ Suicide” got me interested to read the book. The title relates to the book itself because the book itself talks about a bit of evolution of life‚ the sexual reproduction‚ and the process of

cellular respiration are glucose and oxygen. Cellular Respiration‚ process in which cells produce the energy they need to survive. In cellular respiration‚ cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of their activities—to grow‚ divide‚ replace worn

of the blood. To compensate‚ the brain sends chemical and electrical impulses to the muscles. These impulses tell the muscles to begin to contract and relax at very high intervals. This is commonly known as shivering. The production of Adenosine Triphosphate or ATP in the mitochondria of the muscles produces heat. If the body temperature does not rise immediately after this‚ then a second function begins. The brain will signal the blood vessels near the skin to constrict or narrow in diameter

What is passive transport? Passive transport is the movement of substances across the cell membrane without the use of energy by the cell. During passive transport‚ substances move down their concentration gradient‚ hence no energy is required. Passive transports can happen through three different channels‚ namely 1. lipid bilayer 2. pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low

education we have been learning the use of the three energy systems and how they are used in the game of touch football and how they function together. To understand the energy systems‚ our class went through a number of fitness tests. The Adenosine Triphosphate (ATP) stores in the muscle and lasts for approximately 2 seconds and the resynthesis of ATP from Creatine Phosphate (CP) will continue until CP stores are used up‚ which is approximately 4-6 seconds. This gives us around 5-10 seconds of ATP
