CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

The first cholesterol promoter is the dietary cholesterol. When intracellular cholesterol concentration decreases the (sterol regulatory element-binding proteins)SREBP and (SREBP cleavage-activating protein)SCAP is escorted to the Golgi complex .There‚ two proteolytic cleavages of SREBP release a regulatory fragment which enters the nucleus and activates transcription of its target genes‚ including HMG-CoA reductase ‚LDL receptor protein and a number of other proteins needed for lipid synthesis.(3)

citric acid cycle can use. First each pyruvic acid loses a carbon as CO2. The remaining fuel molecules each with 2 carbons left are called acetic. The oxidation of the fuel generates NADH. Lastly each acetic acid is attached to a molecule called coenzyme A (CoA)‚ an enzyme from the formed from the B vitamin pantothenic acid to form acetyl CoA. The CoA escorts the acetic acid into the first reaction of the citric acid cycle. The CoA is then stripped and recycled. The third stage is electron transport

Fat and Water Soluble Vitamins SCI 241 Nutrition Stacey Peterson November 24‚ 2013 Fat and Water Soluble Vitamins Vitamins are organic compounds that are essential to many functions in the human body and classified in two different classes based on their solubility. The B vitamins and vitamin C are water soluble and vitamins A‚ D‚ E‚ and K are fat soluble (Grosvenor & Smolin‚ 2012). These classes are fat soluble and water soluble. According to Grosvenor‚ M & Smolin‚ L. (2012) small

two molecules of pyruvate that each have three carbons inside it. For one glucose molecule in glycolysis were going to make 2 ATP and a chemical called NADH. The pyruvate is going to diffuse into the mitochondria and will convert into acetyl CoA (coenzyme A) which now turns into a 2 carbon molecule. That 2 carbon molecule then goes into the Kreb cycle and releases carbon dioxide. In the Kreb cycle we’re also adding a little bit of energy into NADH and FADH2 that have high energy electrons. NADH and

JBT Task 5 (0515) Fat‚ which is commonly defined as oil‚ have both good and bad affect on our overall health. No matter what type of diet plan we follow‚ we do intake some amount of fat with our diet. Fat‚ overall‚ is good for our health as it is a type of nutrient that helps body drives energy. At the time of any physical activity‚ our body uses calories from fat to keep the body moving and to keep is energetic. We feel drained out when our body is out of energy‚ which often happens in the case

Insomnia‚ a sleep disorder‚ is characterized by arduousness falling or staying asleep. This disease affects individuals nationally; more than 50 percent of the population undergoes this disease and teenagers and younger children comprise of about 25 percent of the population suffering from insomnia‚ making it a substantial disease to be indoctrinated about.

Vitamin B6 is important for amino acid metabolism as well as energy production. Folate is a coenzyme that is needed for cell division. Vitamin B12‚ only found in animal foods‚ is needed for nerve function and to activate folate. Vitamin C is needed to form connective tissue and acts as a watersoluble antioxidant.
