three steps within those stages. The first is the anaerobic stage takes place in the cytoplasm right outside the mitochondria, which is called Glycolysis. During which, the glucose molecule is broken down into two pyruvic acids. Then it passes the oxygen molecules and enzymes on while producing two molecules of ATP. Some microscopic organisms, like yeast and bacterium, can only use this process of respiration because they don't have the necessary components for the next the next stage in the…

produce ATP (Campbell 2011). ATP is used as energy in the synthesis of light or also known as Photosynthesis . ATP is used by photosynthetic organisms to produce their own food and also by performing cellular respiration. It needs mainly glucose and oxygen that involves the transfer of electrons in a chemical reaction. Cellular respiration is the process of producing energy from the food. (McKean D.G. and Hayward D. 2014). Yeast, is composed only of a single cell, but has all the…

Quillin Honors Biology, Block 5 11/01/17 1. The equations are the opposite of each other. Photosynthesis uses sunlight to convert foods from carbon dioxide and water light energy into a six-carbon simple sugar, and also produces oxygen. While cellular respiration uses the oxygen and sugars to release chemical energy for the cells to use, and also produces water and carbon dioxide. 2. The rate at which photosynthesis occurs needs to be higher because photosynthesis creates building blocks for…

The first is the “Investment” stage. As you consume food, glucose is consumed and passed through the cytoplasm. In order for the investment stage to begin, you need to use energy to start it. Unlike the other two processes, Glycolysis does not need Oxygen to function. The only form of energy our bodies can process is ATPs, which stands for Adenosine Triphosphate. Your cells need to spend two of these to start the process. Enzymes are then created and changes the glucose to Glyceraldehyde…

up. This will shape your overall experience. What does it mean to 'let it breath?' The science behind using a red wine decanter lies in the need for it to breath. Breathing just relates to the necessity of wine to come in contact with oxygen. The oxygen allows the alcohol in the wine to dissipate…

Near bottom waters would have higher TAN concentration because of decaying organic matter on the bottom. These waters would also generally tend to have lower oxygen concentrations and higher salinities. When natural upwelling events happen, these colder, high TAN and low oxygen waters would be brought up to the surface. Majority of this TAN would also be in the form of toxic unionized ammonia NH3 as pH of the water would be higher in saltwater environment. So, care…

Combustion of Alkanes What is combustion? Combustion is a chemical process where a fuel reacts with oxygen and releases heat. The fuel can either be a solid, liquid or gas and the oxidizer, the source of oxygen can also be a solid liquid or gas. A new chemical substance is created from the fuel and source of oxygen. These new chemical substances are referred to as exhaust. For combustion to occur, a fuel, oxygen and heat are required. In an alkane, the more carbon atoms that are present, the…

buffer throughout the experiments conducted. This was done to observe the effect different levels of pH buffers have on the breakdown of hydrogen peroxide and the volume of oxygen released. The results from the majority of experiments conducted reflect that though they are in consensus with the hypothesis that the volume of oxygen will be at its highest at pH 7, it was found that the temperature of hydrogen peroxide and the batch of catalase may have varied which affected the precision of the…

adult does. Instead, the fetus draws its oxygen from the mother’s blood where the oxygen content is low. The hemoglobin in adults consist of two alpha and two beta subunits. Fetal hemoglobin consists of two alpha and two gamma subunits. This allows hemoglobin to bind oxygen with higher affinity compared to adult hemoglobin, allowing the extraction of oxygen from maternal circulation. It Is important in fetal development because fetal hemoglobin is the main oxygen transport protein during the…

Oxygen is an essential element is cellular metabolism, and it is readily available in the atmosphere. However, oxygen must be transported from the atmosphere to the cells for it to be used in metabolism. It is transported by blood through the circulatory system. It is the hemoglobin inside the red blood cells that is responsible of binding the oxygen. A hemoglobin consists of four sub units and therefore it can be termed as a tetramer. This tetramer is made of two dimers known as alpha-beta…
