SBI4U-C 1 Lesson Introducing Biochemistry 1 Lesson 1 Biology SBI4U-C Introduction If you think about it‚ living things are made up of chemicals. The cells‚ tissues‚ organs‚ and organ systems that together make up a functioning organism are all the product of interacting chemicals. In order to understand how the organism functions‚ you must also recognize how these chemicals function. The study of the chemicals that are involved in living things is known as biochemistry

RENEWABLE ENERGY RESOURCES ABSTRACT The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e.‚ coal‚ petroleum and natural gas) and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy

charge Q‚ are hung on strings 35 cm long and suspended from one point. They form a 40 angle between them. What is charge Q? Ans: 0.107 C 5. A proton is placed in a uniform electric field. What must be the magnitude and direction of this field if the electrostatic force acting on the proton just balances its weight? The mass of a proton is 1.67 x 10-27 kg Ans: 1.02 x 10-7 N/C‚ up. 6. Find the resultant electric field strength at point P as shown below. Ans: 7.20 x 106 N/C‚ 56

Woodly Biennescar Chapter 7 Interpret the role of electrons‚ electron carriers‚ and ATP in energy metabolism Electron carriers are used for soluble that moves electron from one molecule to another. Electron aids in the gradual‚ stepwise release of the energy from oxidation‚ rather than rapid combustion. ATP power the activities that requires work --- one of the most which is movement. Explain the purpose of oxygen in respiration Without oxygen‚ cellular respiration could not occur because oxygen

Chapter 14 Outline * 14.1 The Nature of Acid and Bases * Acid-Base Theories * Arrhenius- Acid is a hydrogen producer and a base is a hydroxide producer * Bronsted-Lowry- Acid is a proton donor and a base a proton acceptor * Lewis- An acid is an electron pair acceptor‚ and I base is an electron pair donor * Conjugate base & acids * Ka= [products]/[reactants] * Acid dissociation constant * 14.2 Acid Strength * In a strong

are caustic on organic matter and react violently with acidic substances. Also bases can are bitter in taste. And the pH of a basic solution at standard conditions is greater than seven. Strong bases are a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of a very weak acid in an acid-base reaction. Example of a strong base is lithium hydroxide‚ calcium hydroxide and strontium hydroxide just name a few but there

processes that are moving particles down their concentration gradients. A vital active transport process that occurs in the electron transport process in the membranes of both mitochondria and chloroplasts is the transport of protons to produce a proton gradient. This proton gradient powers the phosphorylation of ATP associated with ATP synthase. Osmosis Osmosis is a special example of diffusion. It is the diffusion of water through a partially permeable membrane from a more dilute solution

John Dalton is a chemist who was born on September 6‚ 1766‚ in Eaglesfield‚ England. In 1803 John Dalton created the Dalton’s Atomic Theory. When Dalton’s atomic theory was created chemists believe his ideas were untrue. Even though Dalton’s atomic theory is two centuries old scientist still question to this day whether his theory has been proven correctly or incorrectly. There appear to be many articles out there pointing out what was inaccurate about his theory. However‚ still to this day chemist/people

(3) Six important strong acids include HCl‚ HBr‚ HI‚ HNO3‚ HClO4‚ and H2SO4. (1) Monoprotic acids‚ like the first five strong acids listed‚ have one proton that will ionize in aqueous solution. H2SO4 is a diprotic acid‚ and has two protons that will dissociate in water. (1) In aqueous solution‚ a more stable ion is formed when the donated proton H+ from a strong acid bonds with water to form the hydronium ion H3O+. (2) This is illustrated with the

automotive industry - The automotive industry has three major sectors: assembly of motor vehicles‚ component parts manufacturing‚ and motorcycle assembly. There are 14 motor vehicle assembly and manufacturing plants including two national car projects: Proton‚ which manufactures passenger cars; and Perodua‚ which produces passenger and commercial vehicles. Nine companies are involved in motorcycle assembly. Other car plants include Nissan‚ Toyota‚ and KIA. There are more than 350 automotive component
