GREAT METABOLIC CHALLENGE Metabolism is a series of vital biochemical processes that take place in order to sustain life. During a marathon run‚ the individual relies on the breakdown of carbohydrates and lipids‚ in order to provide energy release in the form of Adenosine Triphosphate (ATP). This essay will focus on the role of mobilization and structures of both carbohydrates and lipids in the production of ATP. Mobilization of Carbohydrates When carbohydrates are consumed during a meal‚ catabolism

catalytic properties and deactivating them (permanently). This therefore restricts substrates being broken down by enzymes to allow the human body to function properly since the heavy metals take similar pathways to that of essential nutrients. Metabolism and any sort of necessary chemical processes will not be preceded properly and therefore the maintenance of the living state of cells will prove to be futile as eventually they will die. (Not receiving what they require in time since enzymes speed

Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

proteins. Proteins provide structure and function and have the chemical structures of Carbon‚ Hydrogen‚ Oxygen and Nitrogen. Proteins have various functions such as making and breaking chemical bonds‚ transport‚ movement‚ signaling‚ regulation and metabolism (cellular process). Peptide Bonds are important while discussing proteins. Peptide Bonds are covalent bonds that join 2 amino acids‚ amino acids are also proteins monomer. Next are Carbohydrates. Carbohydrates incorporate Carbon‚ Hydrogen and Oxygen

ketogenic diet is commonly employed to successfully treat some ailments--notably epilepsy in children--its safety over the long-term has remained an under-researched and controversial topic. What are the consequences of a persistently altered metabolism? A 2010 study carried out at Johns Hopkins Medical Institutions found no evidence of significant side effects after a long-term high-fat dietary regimen among epileptic patients. Scientists tracked 101 young patients at the Johns Hopkins Children’s

Scientific concept: Homeostatic mechanisms use negative feedback to regulate a normal condition. Whether a positive or negative change from the normal condition occurs‚ the body counteracts it to restore the norm. [ Refer to figure 1 in annex below ] Osmoregulation is the process where the body regulates a constant blood water potential by controlling its water and solute concentrations. [ Refer to figure 2.1 and 2.2 in annex below ] Daily life application: Homeostasis is crucial to an organism

1. ATP is made up of ribose‚ adenine‚ and phosphate. It is also made in the mitochondria. ATP plays a very critical role for all organisms from the simplest to the most complex. ATP is like a natural fuel source with out it you wouldn’t be living. ATP enables you to move your muscles and they are building blocks for more complex molecules. Nutrient alone aren’t enough for the body and are of a low energy source but to activate all the nutrients to turn it into a high energy you need ATP. ATP powers

Differentiate between citric acid cycle and glyoxylate cycle. Relate citric acid cycle as energy source. The Central Role of the Citric Acid Cycle 3 processes play central roles in aerobic metabolism. The citric acid cycle. Electron transport . Oxidative phosphorylation. Metabolism consists of: Catabolism: the oxidative breakdown of nutrients. Anabolism: the reductive synthesis of biomolecules. • The citric acid cycle is amphibolic that is‚ it plays a role in both

are used up before lipids with carbohydrates being predominantly used at the 5min mark and lipids being mainly used at the 45min mark. This may be due to the fact that carbohydrates compared to fatty acids can be more readily converted since the metabolism process is much simpler. Carbohydrates do not have to be transported to the muscle cells since they are already present within the cells themselves while fatty acids are not. Fatty acids also require many additional processes for them to enter the
