Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

In the book of biology of Mrtinez and Nazareno‚ there are nine characteristics of life just said and those are : a. Living things are highly organized and
Free Cellular respiration Adenosine triphosphate Metabolism
Cellular respiration is defined as a complex process in which food molecules are broken down to harvest chemical energy which is then stored in the chemical bonds of adenosine triphosphate (ATP). It is usually decided by the metabolic exercise and the equivalent amount of ATP discharge. As long as the extracellular O2 pressure surpass a demanding value ranging from 3-6 torr‚ studies have proof that cellular oxygen uptake stay permanently autonomous of oxygen tension. When the carbon-hydrogen bonds

The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry‚ those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper‚ chemistry can be seen everywhere. However‚ most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread‚ once consumed‚ can turn into fuel for the human body

occurs when yeasts is added to a solution of glucose and water. Fermentation starts with a process called glycolysis. In glycolysis Glucose is broken down into two molecules of pyruvate and a net yield of 2 NADH (electron carrier) and 2 ATP (adenosine triphosphate) molecules. The first step of glycolysis is the energy investment phase. In which 2 ATP’s are added to the Glucose molecule‚ which produces 2 ADP’s and Fructose 1‚ 6-biphosphate. This is followed by the energy payoff phase. In this phase NAD+

Usually‚ this energy is in the form of adenosine triphosphate‚ or ATP. Cellular respiration is the process that synthesizes ATP through the three main steps of glycolysis‚ the citric acid cycle‚ and oxidative phosphorylation. Essentially‚ the sugar glucose is obtained by an organism and put through several

organelles located in the cytosol of cells and is believed to have originated through an endosymbiotic relationship. The unique double layered membrane structure is responsible for the production of the primary energy currency of the cell; adenosine triphosphate or ATP. Small amounts of ATP that the cell can immediately use as an energy source are available during glycolysis of glucose to pyruvate‚ but the amount of ATP derived from pyruvate can be greatly increased through further processing. Through
Premium Adenosine triphosphate Metabolism Cellular respiration
Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get its energy by anaerobic respiration because much of the
