<p>Introduction</p><p>Teacher asks Students. Brainstorm: Why do we need energy for living organisms? </p><p>Answers attach to the board: movement, respiration, sensitive, growth, reproduction, excretion, nutrition</p><p>How cell uses energy stored in food?</p><p>Your cells require energy to carry out many different processes (active transport across the membrane, protein synthesis, and cell division). The fuel for these functions comes from a molecule called adenosine triphosphate (ATP). ATP stores energy until a cell needs it. When a cell requires energy, it breaks part of the ATP molecule apart which releases energy.</p><p>Our topic is Structure and functions of ATP.</p><p> Aim (purpose) of lesson You will be able to describe the structure and functions of ATP. </p> | |

<p>Terminology</p><p>Teacher explain how pronounce new terms of lesson. Teacher asks Students to repeat all together after him/her, Teacher must give clear pronunciation of terms. Do this 2 times, and try to ask individual Students to pronounce terms </p><p>Students listen to teacher, repeat words 2 times, some students pronounce words individually.</p><p>Work with text </p><p>Structure of ATP ATP consists of adenosine and three phosphate groups. Adenosine is a combination of adenine and ribose sugar. Adenosine can be combined with one, two or three phosphate groups to give, in turn, adenosine monophosphate (AMP), adenosine diphosphate (ADP) or adenosine triphosphate (ATP). Function of ATP Energy cannot be produced and destroyed, it is converted from one state to another. When or-ganic molecules are broken down by series of reactions. They release chemical potential energy, which is used to synthesize ATP. The phosphate bonds of ATP are extremely en-ergetic or macroergic bonds. They are known as high energy bonds. When a phosphate group is removed from ATP, adenosine diphosphate (ADP) is formed and 7.3 kcal of energy is released. Removal of a second phosphate produces adenosine monophosphate (AMP), and 7.3 kcal of energy is released again. Removal of the last phosphate, leaving adenosine, releases only 2 kcal of energy. </p><p>Worksheet 1 Students read text one by one, translate sentences </p><p>Activity</p><p>Teacher gives instructions. Show ATP structure on the board. Students divide into groups and create a dynamic model of ATP. Ask the group to build a model of ATP, and then break them down into adenosine diphosphate (ADP) and adenosine monophosphate (AMP), then re-connect. </p><p>Students do this task in groups, when they finish the job they go to the Board and defend their poster Play Doh, cardboard, colored paper, or sets for molecules construction (for chemistry lessons) Paper, markers </p><p>Physical minute</p><p>Make a circle, now we play with balloon. You must throw the balloon to your friends and name the term (in Russian, in English) – they must translate. I start – we will continuous …</p><p><br></p> | |
