CATABOLISM ANABOLISM Energy source (glucose) Cell structures (cell wall, membrane, ribosomes, surface structures) Energy Macromolecules (proteins, nucleic acids, polysaccharides, lipids) Energy Subunits (amino acids, nucleotides, monosaccharides, fatty acids) Energy Precursor metabolites Waste products (acids, carbon dioxide) Nutrients (source of nitrogen, sulfur, etc.) Catabolic processes harvest the energy released during the breakdown of compounds and use it to make ATP. The Anabolic processes (biosynthesis) synthesize and assemble subunits of macro- processes also produce precursor metabolites used in biosynthesis. molecules that make up the cell structures. The processes use the ATP and precursor metabo- lites produced in catabolism. FIGURE 6.1 The Relationship Between Catabolism and Anabolism Precursor metabolites are compounds produced during catabolism that can either be further degraded or be used in anabolism to make the subunits of macromolecules.

Activity: Research Macronutrients and Bioenergetics, comparing CHO energy vs. Fats/Proteins. Outline & discuss why CHO is our primary fuel source and should compose the majority of total calorie intake (≥60-65%), specifically for those participating in regular physical activity, excercise, and/or sport. Dispell the myths about Protein and Fat.

Nutrition has been one of the major problems that our country is facing most specially in this time of pandemic. As one of the trusted chemists of the Local Government Unit you were tasked to make an ideal meal plan that will serve as a “meal guide’ for families in preparing their daily meals. Your food pyramid must show the BIOMOLECULES of life for each level (GO, GROW, GLOW and FLOW foods). You must also show sample computations of carbohydrates that will take place once the specific food in the food group is digested, this is to show your audience an evidence on how important your food pyramid is. You must present your work using a multimedia presentation.    In line with this task, the following must be prepared:    list of biomolecules in your meal plan; (TEST 1)  computation of chemical reaction that will take place once digestion happened; (TEST 2)  narrative/description that will explain and convince your reader on the importance of your food pyramid. (PRESENTATION –…
Purpose: The purpose of this assignment is to explain how energy is extracted from foods ands used to produce ADT and also describe how the body synthesizes new molecules.
Background“Eat eggs and exercise to live longer! ”Obviously, this ‘headline’ is fictitious, but it got your attention, didn't it? Reports of new research findings in the area of food andhealth seem to get a lot of media coverage, after all, food and health issues are of interest to nearly everyone. Reporters,academics, and health professionals all want the latest information —as do consumers. A single study and the reports surroundingit can send many people in search of the latest food or supplement holding the promise of good health.Frustrated and confused by the tremendous amount of food and health information reported nowadays , many people wantsimple certainties to help them protect their health through diet. The trouble is that single studies rarely provide such certainty,although they often get big headlines.The media, health professionals, and educators are the gatekeepers of today's food and health information. They have a largeinfluence on what consumers hear, read, and…
Energy Drinks and Soda 1) Pick an energy drink or soda. Examples: red bull, 5 hour energy, monster, rock star, Coke, Pepsi, etc.. 2) Review the ingredients- list which are familiar from class (ex: thiamin, a B vitamin), and which ones we have not covered as nutrients (ex: guarana, taurine). All ingredients should be categorized. And then answer these questions Why are nutrients we have covered, such as B-vitamins, included in these beverages? Do you think ingredients in these drinks are regulated? How much caffeine is in the drink compared to 1 cup (8oz) of coffee? Does your drink have weight loss claims? What claims are on the package? Are you comfortable consuming energy drinks and soda? Do unfamiliar ingredients concern you?
