My name is Natalie and I am a exercise and sport scientist with a passion for science communication. During my studies I discovered how confusing, inaccessible (and often boring) research is to the public, which has resulted in the exponential rise in myths, misconceptions and/or lack of knowledge. I created this page to translate confusing scientific jargon into digestible and comprehensible formats such as graphics and video's. Follow along for your daily dose of knowledge. Feel free to ask for any topic you would like me to explain and questions you may have! You can also find me on Instagram, Twitter and facebook as @sportscicomm 💫 Follow me on my other socials: Instagram: www.instagram.com/sportscicomm Twitter: www.twitter.com/sportscicomm Thank you so much for watching ! and PLEASE, feel free to ask any questions you have below Video Summary: Bioenergetics is the flow of energy in biological systems. The human body requires a constant supply of energy to power physical activity. The first law of thermodynamics states that energy cannot be created or destroyed but is transferred from one form to another. In the human body, energy is transferred through a compound called ATP. ATP consists of a molecule of adenine and ribose linked to 3 phosphates. The energy in ATP is stored in the bond that links the 2 outermost phosphates. The energy is released from ATP through Hydrolysis, a process that splits ATP into ADP, an inorganic phosphate, a Hydrogen ion. The hydrolysis or splitting of ATP occurs without oxygen releasing energy rapidly. This released energy stimulates our muscle fibers to contract required for exercise. The body requires a constant and continuous supply of ATP. Our muscle cells contain a small amount of ATP, termed intramuscular ATP, that can be released rapidly to power the start of exercise, however, this intramuscular ATP is limited and is depleted after a few seconds of exercise. To overcome this storage limitation, at the onset of exercise, our body activates three metabolic pathways that work to continually resynthesize ATP at its rate of use: The phosphates system, the glycolytic system, and the Oxidative system.
