Lecture 13 Nutritional Requirements The Nutrient and Nutrition. Classes of nutrients: carbohydrates‚ fats‚ proteins‚ vitamins‚ water‚ minerals. Function‚ sources and deficiency/toxicity of major vitamins and minerals. The Nutrient and Nutrition Humans are heterotrophs‚ organisms that cannot produce their own food. Heterotrophs must ingest‚ or take in‚ food. At least 95% of the species of organisms on earthall animals‚ all fungi‚ and most protists and bacteriaare heterotrophs

Carbs can be converted to fat‚ however lipogenesis from glucose is less effective o Weight gain from CHO thought to be caused by sparing lipolysis rather than direct CHO lipogenesis o PDH Complex main link of glucose metabolism to FA synthesis (pyruvate acetyl CoA) Most AAs can serve as precursors for fat synthesis

Metabolism is the sum total of chemical reactions within cells. 2. In metabolic reactions‚ the product of one reaction serves as starting materials for another metabolic reaction. 3. This chapter explores how metabolic pathways supply a cell with energy and how other biochemical

Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three stages are: glycolysis‚ citric acid cycle‚ and electron

in shape if certain factors such as temperature‚ pH or substrate concentration change‚ and so the active site of the enzyme may no longer compliment the base of the substrate therefore fewer complexes can form and the reaction rate drops. Coenzymes are organic compounds‚ often containing a vitamin molecule as part of their structure they are not permanently bound to the enzyme but are temporarily bound for the duration of the reaction and then move away once it is completed.

The standard deviation for higher temperature was 7.91 mL/g/hr‚ which was higher than the standard deviation for lower temperature which was 1.92 mL/g/hr. The Q10 for the oxygen consumption was 4.39. In the graph‚ the standard deviation for higher temperature was more stretched out than the standard deviation for lower temperature. Although‚ the mean was higher for higher temperature but the standard deviation

A cycle is defined as any complete round or series of occurrences that repeats or is repeated in the same order and at the same intervals. The natural existence of cycles is highly important without cycles resources would run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each
