Question

An element that aids releasing energy in the cell ___________________ ammonia A compound that is released by the decomposition of living organisms ____________ ammonia The chemical term organic means that the molecules of a compound contain the Mom carbon. Living systems contain compounds of carbon atoms. Therefore, living systems are called organic. There are three basic organic compounds found in living systems: carbohydrates, lipids, and proteins. Carbohydrates contain the elements carbon, hydrogen, and oxygen. The hydrogen and oxygen atoms occur in the same ratio water, two hydrogen atoms to one oxygen atom (H_2 O). A small molecule of carbohydrate is called a simple sugar. An example of a simple sugar is glucose. The chemical formula for glucose is C_6 H_12 O_6. How many carbon atoms dies glucose have ? _______________ How many hydrogen atoms does glucose have? _____________ How many oxygen atoms does glucose have? ______________ C_6 H_12 O_6 These smaller carbohydrate molecules can be linked together to form larger molecules of starch and cellulose. Starch and cellulose may be broken down into smaller carbohydrate molecules and eventually into simple sugar. Carbohydrates store energy for the cell. Sugar and starch are the basic energy sources for the cell. Large carbohydrates such as cellulose strengthen the cell structure. Example: the cell walls in plants are made of the carbohydrate cellulose. A large molecule that belongs to the class of organic compounds called carbohydrates is called ______ starch or cellulose Starch and cellulose may be broken down (digested) into molecules of ___________ simple sugar (glucose) Carbohydrates contain the chemical elements ___________, _____________, and ___________. carbon, hydrogen, and oxygen Lipids also contain the elements carbon, hydrogen. and oxygen. Two kinds of lipids are fats and phospholipids.

Explanation / Answer

12.Yes ammonia is a fuel source for cells because of the presence of hydrogen atoms in it.

13. On decomposition,ammonia is released.the decomposition causes release of nitrogen as a waste and this nitrogen is present in form of ammonia.

14. The compounds that contains carbon are called organic compounds.
