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
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.
Proteins are an essential part of all living organisms. Proteins are macromolecules made up of amino acid chains. These chains of amino acids are held together by peptide bonds to from polypeptide chains. Each proteins function is determined by its own unique three dimensional shape and active site. Proteins have multiple functions that are important to all cells.

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.
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
The kinetic energy depends on mass and speed. Every atom and molecule will have kinetic energy. This energy will always be transferred and never destroyed as mentioned in the laws of thermodynamics. The law of thermodynamics states that when work is done and heat is created, internal energy changes according to the law of conservation of energy. In return, the energy stored becomes potential energy.
In Chapter 14, kinetics of particle, work and energy, we could summary this chapter explain us about the moving particle based on the principle of energy that involves force (F), velocity (v) and displacement (s). By these kinds of units, we could solve the problems that involve power (P) and efficiency (ε). In this chapter also explained us about conservation of force and theory of conservation of energy due to solve the problems of kinetic energy. While in Chapter 18, kinetics of rigid, work and energy, we could summary this chapter almost got the same explanation by the chapter 14 which was it contain about work of force, kinetic energy, gravitational potential energy, elastic potential energy, conservation of energy and principle of work and energy. If we study deeply about these two chapters, we could get the similarities and differences about the work and energy by the
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.
Hello Professor Rode, and class. Overall, I would like to say that this class has been pleasant and a learning experience towards the career I want to fulfill in becoming a Clinician-Registered Dietitian. My favorite course assignment for this term was unit five, because I was able to research and learn the most out of that assignment about Nutrient Analysis databases and programs that are out there. I believe, that I can take that resourceful information and utilize it in both my professional career and personal.
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).
Diet and Analysis 1 Since the beginning of this assignment, I had three goals in mind. The first goal was to cut down on pork. This is something that I knew would be extremely difficult for me but it was something that needed to be done. The first week was easy, I consumed a lot of chicken and ate some salmon one day. Salmon is very expensive unlike pork, so I cannot eat salmon regularly but I ate it nevertheless and it was a good alternative for pork for the time being.
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.
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
