ENERGY FOR LIFE Paul Torres, Nicole Julieta Velasquez, Erika Salazar, Caroline Cuevas.

TRAPPING AND USING ENERGY  If an enzymes attaches to a large molecule it will help it change Chemical reactions of metabolism need enzymes The total of all chemical reactions in an organism. An enzyme is a type of protein that speeds up chemical reactions in the body.

PHOTOSYNTHESIS Photosynthesis is the process in which a plant makes its own sugar to grow. The sugar that a plant makes is called glucose. Plants and many other producers can convert light energy. Organisms that cannot produce their own food are called consumers.

PRODUCING CARBOHYDRATES Chlorophyll is needed for photosynthesis. Enzymes are also needed for this process. The powered light energy powers chemical reactions that produce sugar and oxygen from the raw materials, carbon dioxide and water. Producers that use photosynthesis are usually green because they contain a green pigment called chlorophyll

STORING CARBOHYDRATES Plants make more sugar during photosynthesis than they need for survival. Excess sugar is changed and stored as starch, or used to make other carbohydrates. Plants use these carbohydrates as food for growth, maintenance, and reproduction.

CELLULAR RESPIRATION During cellular respiration, chemical reactions occur that break down food molecules into simpler substances and release their stored energy. Just like photosynthesis enzymes are needed for this action.

BREAKING DOWN CARBOHYDRATES The most easily broken down food molecules are carbohydrates. Cellular respiration begins in the cytoplasm of a cell. The carbohydrates are broken down into glucose molecules. Each glucose molecule is broken down into simpler molecules,(which are also broken down even more), and made into energy.

FERMENTATION When cells do not have enough oxygen for cellular respiration, they use a process called fermentation. Like cellular respiration, fermentation begins in the cytoplasm.

RELATED PROCESSES All of these actions are related, every living thing uses them for a reason.

QUESTION Explain different ways a cell can trap and use energy. The simplest answer is from the food you eat, because the chemical energy stored in food molecules is changed inside of cells into forms needed to perform all the activity's necessary for life
