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

approximately 9.1 minutes for a man with 54 ml/kg oxygen uptake to run 1.5 miles. Oxygen uptake (or VO2) is a measure of the volume of oxygen that is used by our body to convert the energy from the food you eat into the energy molecules‚ called adenosine triphosphate (ATP)‚ that your body uses at the cellular level. VO2max (or maximal oxygen consumption) is simply the maximum possible VO2 that a given person can achieve. VO2 and VO2max are important in the context of exercise‚ because they are a measure

8.1 The totality of an organism’s chemical reactions is called metabolism. Metabolism is an emergent property of life that arises from interactions between molecules within the orderly environment of the cell. a. The chemistry of life is organized into metabolic pathways Metabolic pathways begin with a specific molecule‚ which is then altered in a series of defined steps to form a specific product. A specific enzyme catalyzes each step of the pathway. Catabolic pathways release energy by

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

certain anabolic and catabolic reactions take place. The three main energy systems are ATP Pcr‚glycolytic and oxidative; oxidative having three futher subgroups. These are discussed below ATP Pcr The ATP Pcr system is a constituent of Adenosine triphosphate and phosphocreatine. This energy system provides high energy in minimal time. The stored phosphates contain excessive/high energy which are broken down upon activity therefore releasing energy at a very fast rate. However‚ it experiences

oxydation reactions is used to form adenosine triphosphate ( ATP )‚ the Energy currency of the cell. 5. Name the two initials steps in glycolysis. The initial steps are the additions of two phospates to the glucose molecule at the expense of two molecules of ATP. 6. What are the three molecules that results? The three molecules that result are a 6 carbon sugar diphosphate molecule and 2 low energy adenosine diphosphate molecules. 7. What then occurs
