Essays on Respiration

Photorespiration is the opposite pathway to photosynthesis, where the protein RubisCO, which is highly abundant on earth, adds or consumes oxygen from the 5 carbon sugar rubisco bisphosphate instead of utilizing carbon dioxide. This enzyme acts as both a carboxylase and an oxygenase and cannot differentiate between carbon dioxide and oxygen molecules. RubisCO has a…

Cellular respiration begins with glucose. Glucose is the primary fuel used in glycolysis, the first stage of cellular respiration. This molecule is found in the gel-like substance called cytoplasm that fills the cell. In glycolysis, glucose undergoes phosphorylation by ATP. The ATP is converted back to ADP. The glucose molecule is rearranged and undergoes a…

Cellular Respiration Lab Essay, Research Paper Introduction This lab was done to find the relationship of gas production to respiration rate. Justin Pyka and I did the lab on December 12th, 2000 in Mr. Myers ’ room. The lab was done with hibernating pea seeds and shooting pea seeds. It was done to prove the…

In order to find the consequence of the substrate on the rate of respiration of barm. Durham trial tubing method was used in the first experiment. In this method two trial tubings was obtain. where trial tubing one contains distilled H20 with the 7 milliliter substrate glucose while trial tubing two contains distilled H20 and…

AbstractThe purpose of this experiment is to design and conduct a basic scientific experiment, identify and control variables. Some other objectives that we learned is to write a formal hypothesis, identify the basic and integrated process skills of science that were used in this experiment. Also, we will learned the effects of temperature on goldfish…

Several principles govern metabolic pathways in the cell: Complex chemical transformations in the cell do not occur in a single reaction, but in a number of small steps that are connected in a pathway. Each reaction is catalyzed by a specific enzyme. Metabolic pathways is catalyzed by a specific enzyme. Many metabolic pathways are compartmentalized,…

INTRODUCTION Respiration is essential for all organisms and can be simplified as “breathing”. However, the exact definition of respiration varies depending on the specific type being discussed. The exchange of gases, such as carbon dioxide and oxygen, that is vital for the body’s functioning is referred to as “Respiration”. Oxygen is necessary for sustaining life….

R.S. is a long-time smoker who developed bronchitic chronic obstructive pulmonary disease (COPD). He also has a history of coronary artery disease and peripheral vascular disease. His arterial blood gas (ABG) values are pH = 7.32, PaCO2 = 60 mm Hg, PaO2 = 50 mm Hg, HCO3 – = 30 mEq/L. His hematocrit is 52%…

In this lab the effects of different substrates on the rate of cellular respiration is being put to a test which is a very interesting experiment. The three major substrate solutions being used for this experiment are glucose, maltose, and alanine. The issues this experiment addresses are cellular respiration occur in different stages which are…

Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP. Oxidative phosphorylation uses the electrochemical gradient, set up by the oxidation of nutrients, of protons across the inner mitochondrial membrane to generate ATP from ADP. During oxidative phosphorylation, electrons are transferred from electron donors to electron acceptors…
