apter 7 was about energy, which is the capacity to do work. Within energy there is two sections potential energy which is stored energy, and kinetic energy which is energy that is in motion the total energy in the universe does not change energy cannot be created or destroyed a compound with lower. potential energy is more stable than a compound with higher potential energy. Chapter 7, also discusses the focus on the human body energy in nutrition. This section talks about caloric value of the substance, and how one gram of protein are one gram of carbohydrate typically releases about four cal/gram etc. And how much energy is provided from this.
Chapter 7 also discusses energy changes in reactions, and how breaking a bond requires energy. Bond
Nevertheless, the effects caused by the breakage of bonds will eventually lead to a decrease in the rate of reaction. As seen in the data, the reaction rate increased from 0.088 to 0.101 throughout the interval of -5℃ to 20℃ then decreased to 0.037 throughout the interval 20℃ to 56℃. This can be explained by the fact that 20℃ is the optimal temperature, therefore the active site of the enzyme is complementary to the substrate, causing the rate of reaction to be
coupling- When endergonic reactions utilize the energy that was released from an exergonic reaction. 17. energy of activation-The amount of energy that is needed in order for a reaction to start. 18. entropy-
Kinetic energy is moving energy and can be found through the equation KE=(½)mv². Energy is measured in the units of Joules or j. Potential energy is another form of energy that is energy that has the ability or potential to make matter move once it is released. Energy cannot be destroyed or created, rather is is transformed into other types of energy (for example kinetic to electrical). Mass is also another type of energy (mass energy) and it is just the mass of an object or the energy of being. Chemical changes cause atoms to be altered or changed while physical changes do not affect the chemical state of an object.
I chose this two speech’s by Ethan Crabtree and Ben Everett because they were both similar in the topic. They were about the nutrition of the human body and how Aspartame affects the human body. In this paper, I will be comparing and contrasting the way they were delivered, how much knowledge each one the speakers seemed to have about their topic, and there visual aid work such as, handouts, PowerPoints, and or poster boards. And the highlights of each speech. Ethan’s speech was about how a good balanced diet and exercising can be very advantageous to the health of your body.
Kinetic theory states that molecules are always in constant motion. Kinetic energy and molecule velocity increases as temperature increases. Reactions require collisions between reactant molecules or atoms. In chemical reactions, the reactants change into products when molecule collide with enough energy to break old bonds to make new ones. Collisions increase or become more violent between molecules at higher temperatures or decrease as the temperature is lowered.
With reading ATP 6-01.1 it has helped me to understand the meaning of Knowledge Management and Knowledge Management tools that we use every day without realizing that we are. As a society we are spoiled to the amount of digital information that is so readily available to for us to use. The use of computers, tablets, smart phones are tools that we use every day in the military and in the civilian arena.
He gives an explanation of nutritionism is “decidedly unscientific things” (19) and studying nutrients is “the only thing [nutritional scientists] can do” (62). He explains in detail that the nutrient content of the food depends on the different soil. Different food has so many nutrition, each food has many functions to aid to build the human body stronger. The author reminds us that in nutrition science, much is still a theory and most encouragements need to improve. Also, nutrition science has usually put more of its energies into the idea that the problems it studies are the result of too much of a bad thing instead of too little of a good
Nutritionalism is a topic that is widely researched around the globe, but even more so in America. The topic of healthy food is not only being researched but also heavily debated upon: whether one kind of food is any healthier than another. The debate surrounds an idea that food is the reason for many health disabilities. Because of the debate about food people have been formulating their own ideas and theories about the nutrition of food. Two articles about the nutrition argument are Escape from the Western Diet by Michael Pollan and Food as Thought: Resisting the Moralization of Eating by Mary Maxfield.
Alexandra Fowler Due: 10/25/2015 Metabolism Exam Answer the following questions as completely and concisely as possible. Some answers may be a single word, but for more detailed responses, keep you answer to 3 sentences or less. What is the electron donor of an organism growing chemorganotrophically? The electron donor of an organism growing chemorganotrophically is an organic compound such as glucose, acetate, etc.

Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).

During ATP hydrolysis the enzyme ATPase uses water to cleave a phosphate from ATP producing ADP and a free phosphate which remains attached to the myosin head. The energy that was released from breaking the chemical bond is used to move the myosin head into position for attachment to the actin molecule. Step two of the contraction cycle is Cross-Bridge formation. During cross bridge formation the myosin head attaches to the revealed myosin-binding site on actin forming a cross bridge between the two protein molecules. Step three of the contraction cycle is the power stroke.
Your muscles use this energy to generate mechanical force and also heat. These parts get rearranged in chemical reactions, releasing or adding to this potential
Food, a substance which is consumed to provide nutrition to the body. It is usually obtain from plant or animal and contain many essential nutrients, which includes fats, vitamins and minerals. The food ingested and assimilated by organism and its cells respectively, to provide energy, maintain life and to stimulate growth. We humans have five different types of tastes perception like sweet, sour, salty, bitter, and umami. As humans have evolved, the taste which provide the most energy like sugar and fats are mostly pleasant to eat while others like bitter etc, are not enjoyable.
