During exercise, energy demands increase readily. Heart rate and blood pressure increase to pump blood throughout the body, providing ample amounts of oxygen to the muscle cells. As workload increases, the demand for oxygen increases. As a result, the body becomes depleted of most of its oxygen and energy capacity post-exercise. Muscle oxygenation is needed to increase after exercise to replenish energy loses and to repair the damaged muscle tissues. Glycolysis, the metabolic process of…

The mitogen-activated protein kinase, or MAPK, pathway is a chain of proteins in the cell that relays an extracellular signal from the Ras protein to the DNA in the nucleus of the cell. This pathway consists of multiple phosphorylations as MAPKKK phosphorylates and activates MAPKK which then phosphorylates and activates MAPK. At the end of this cascade, MAPK phosphorylates various effector proteins (Alberts, 557). This signaling pathway plays an important role in cells as it results in complex…

The two major processes that drive the normal functioning of the carbon cycle are photosynthesis and cellular respiration. Photosynthesis is the metabolic pathway that takes raw materials and converts it to sugar. Photosynthesis takes place in the leaves, specifically in the chloroplasts of the cells of plants. Photosynthesis also occurs in plants, green protista, and prokaryotes. There are two phases in photosynthesis, the light dependent and the light independent reactions. Cellular…

Fermentation Rate in Different Sugars Abstract: This experiment is designed by students after studying the process of cellular respiration and fermentation. It demonstrates students’ understanding over the materials and utilization of the lab setting. In this experiment, the primary focus will on the speed of fermentation in different substances (sugars) in the same condition (temperature, volume, amount of yeast). Each solution will be mix with a fix amount of yeast and put in fermentation tube…

9.1 Catabolic pathways yield energy by oxidizing organic fuels Catabolic pathways and production of ATP Fermentation - occurs without O2, is partial degradation of sugars to release energy Aerobic respiration - uses O2 in breakdown of glucose (or other energy-rich organic compounds) to yield CO2 and H2O and release energy as ATP and heat Of some prokaryotes - doesn’t use O2 as a reactant but it 's a similar process Cellular respiration - usually used to refer to aerobic process Is…

Sensitivity of Cancerous C.elegans with Mitochondria Dysfunction Mitophagy is a selective autophagic elimination of damaged or excessive mitochondria, especially when cells are under adverse stress. Mitophagy has been identified as the cause of various human diseases and even cancer. In recent years, researchers gradually regard mitophagy as the target for cancer treatment, although the role of mitophagy in the developmental and metabolic process of cancer is still not clear. In this…

The researchers used two groups of rats: one fed the ketogenic diet regimen and the other a control diet. They found that chronic ketosis resulted in the increased production of mitochondrial proteins as well as proteins associated with oxidative phosphorylation, the cells primary mechanism for producing ATP. The researchers used electron micrographs from the dentate-hilar region of the hippocampus, and visually analyzed the micrographs from ketogenic diet fed rats and control diet fed rats.…

Question and Hypothesis Experiment I Eukaryotic cells contain several membrane-bound organelles. Plant cells are a specific type of eukaryote that are both aerobic and photosynthetic. Because of this, they contain mitochondria that serve a vital role in aerobic respiration that follows photosynthesis. The enzyme succinate dehydrogenase (SDH) is an enzyme associated with the Citric Acid Cycle that takes place in the mitochondrial matrix. SDH serves as a catalyst for a reaction in which succinate…

Professor Fowler The Mode of Inheritance in Nicotiana Tabacu seeds and Albinism Introduction In plants, the chloroplast is an essential organelle for a plant cell’s primary metabolism. Productions such as CO2 fixation, manufacture of carbon skeletons and fatty acids, and synthesis of amino acids from inorganic nitrogen that is important for a plant to live and thrive. (Liu, Li, & Cheng, 2016) In addition, the chloroplast is responsible for producing the color pigment in plants because…

Adria Bollendorf CH-213 Cellular Respiration Level 3 analysis All cells in the body have a need for a source of energy to function. Cellular respiration is a specific set of metabolic relations that occur in cells of organisms to convert biochemical energy as ATP and release products. The reactions of cellular respiration are glycolysis, pyruvate metabolism, Krebs cycle, and electron transport chain (ETC). The pathways are either aerobic meaning they need oxygen to occur or anaerobic meaning…
