An adult eats food whose nutritional energy totals approximately 2100 Cal per day. The adult burns 1900 Cal per day. If 1 lb of fat is stored by the body for each 14.6 103kJ of excess nutritional energy consumed, how long will it take for this person to g...
Fermentation is commonly used in houses to make bread, cheese, curd, and many more food items. Fermentation enhances the flavor, taste, and nutritional value of food products. In addition, fermented foods are rich in good bacteria that help to digest complex food molecules in the ...
The COOH cap is what makes these molecules acids. You are probably familiar with acetic acid because this is the acid found in vinegar. You can see that the fatty acids are like acetic acid, but they have much longer carbon chains. To make a normal fat, you take three fatty acids and...
Digestion involves the mixing of food, its movement through the digestive tract, and the chemical breakdown of the large molecules of food into smaller molecules.Digestion begins in the mouth, when we chew and swallow, and is completed in the small intestine.The chemical process varies somewhat f...
1. Chemical Energy Consumption These types of energies are contained within bonds between molecules. The sources of such energy are coal, gasoline, natural gas, and batteries. 2. Electrical Energy Consumption Electrical energy is present within tiny particles that are charged, which are known as el...
"So far everything looks safe and sound, but the dust could affect the power generation of the solar wings, as the dust is bound to reduce the efficiency of the power generation, which could lead to a shortage of energy," Peng said. In order to generate enough power fo...
The amount of C stored in soils supporting rainfed agriculture is determined by the balance between C inputs – mainly from plant biomass decomposition (Fig. 1c) and rhizodeposition (Fig. 1d) – and losses or outputs – mainly from oxidation/mineralization in addition to erosion and leaching (...
to relate the force-induced deformation of the energy landscape to the force-induced conformational change of the molecular complex (which all other models lack), thereby connecting parameters of the abstract energy landscape to the structural-elastic properties of the interacting molecules in question....
A chemical process used in the browning of food to give it its distinct smell and taste is likely occurring deep in the oceans, where it has helped create the conditions necessary for life. Known as the Maillard reaction after the French scientist who discovered it, the process conver...
How does a food chain show energy flow? How is O2 a pi electron acceptor? What is the role of oxygen in cellular respiration? How are gases transported in insect bodies? What nutrients do cells need to transport into the cell? How is the energy produced by respiration stored? How do the...
