Step by step
Solved in 3 steps
- The degradation of nutrients for energy is also known as oxidative metabolism. True FalseThe purpose of this assignment is to explain how energy is extracted from foods and used to produce ATP and also describe how the body synthesizes new molecules.Starvation will result in a positive nitrogen balance as will periods of growth or repair following an illness. True or False
- True or False Little ATP is produced during initial breakdown of macromolecules that occurs in the gut.describe how each major class of nutrients is chemicallydigested, name the enzymes involved, and discuss thefunctional differences among these enzymes; andExplain why cells need to receive nutrients (explain what nutrients are and give examples).
- The process where a macro-nutrient can be used to synthesize another non-essential macro- molecule or macro-nutrient is known as: O intermediate metabolism O macro-nutrient exchange O intracellular switching O intraconversionWhich of the following is TRUE regarding liver metabolism? Select three of the following: The liver (hepatocytes) has hundreds of functions, such as producing glucose, ketones, fatty acids, cholesterol, proteins, and bile for the rest of the body. Hepatocytes have the GLUT2 antiporter, which allows for secondary active transport of glucose into the cells. Hepatocytes have glucokinase that continually makes glucose 6-phosphate, and it has a lower Km than other hexokinases so it continuously metabolizes glucose when concentrations are low. Glucose 6-phosphate is the "transfer station" in the liver since it can be made my multiple pathways and have multiple fates. The liver converts amino acids to citric acid cycle intermediates or pyruvate for gluconeogenesis. The liver oxidizes fatty acids into glucose, which can be sent to other cells and used for energy or converted into phospholipids and triacylglycerol.Which of the following statements regarding dietary nutrients is FALSE? Macronutrients provide cells with energy whereas micronutrients provide protein cofactors. Water soluble vitamins can be stored long-term. Enriched foods contain synthetic vitamins to replace natural vitamins lost during processing. Fortified foods contain vitamins and minerals not originally found in the foods. The majority of B vitamins must be converted to their active form in the body.
- Discuss the origins, types, and functions of bioelements and nutrients.If a person has a medical condition in which their mitochondria do not function properly, what nutrient will they not be able to use for energy? Group of answer choices Glucose Fatty acids Amino Acids Ketone bodies Cholesterol They would not be able to use any of the above nutrientsA deer eats 25kg of herbaceous material per day. The herbaceous material is approximately 20% dry matter(DM) and has an energy content of 10MJ.(kgDM)^-1. Of the total energy ingested per day, 25% is excreted as undigested material. Of the 75% that isn’t digested, 80% is lost to metabolic waste products and heat. The remaining 20% is converted to body tissue. How MJ are converted to body tissue on a daily basis? Calculate the percentage of energy consumed that Osborn’s converted to body tissue Draw a schematic of energy balance.
