Practice Questions and Answers
Where does Carbohydrate (CHO) originate from? - Ans:✔✔-CHO is a product of plant photosynthesis.
Photosynthesis - occurs in plants. Roots pick up water from the ground. Leaves take Carbon dioxide from
the air. The two elements combined with sunlight emit oxygen. Man needs oxygen.
What is the Role of Carbohydrate (CHO) in the body? - Ans:✔✔-CHO is the primary & preferred source of
energy used to carry out all body functions.
Man gives off carbon dioxide (CO2) & water (H2O) Plants take up CO2; combine it with H2O & sunlight
Man & animals eat plants & breathe oxygen
Describe the carbohydrate cycle that exists between living things and plants? - Ans:✔✔-1. Plants
produce oxygen & complex sugars & starches (02 & CnH2nOn

3. Man gi vest off carbon dioxide (CO2) & water (H2O). Plants take up CO2: combine it with H2O &
sunlight.
What is the overall equation for the photosynthesis that occurs in plants? - Ans:✔✔-6CO2 (Carbon
Dioxide) + 6H2O (Water) --Light--> C6H12O6 (sugar) + 6O2 (oxygen)

BE-What effect do enzyme secretions have on the food entering the digestive system? - Ans:✔✔-
What effect does the mouth have on food entering the digestive system? - Ans:✔✔-The mouth
(including tongue & teeth) mechanically breaks down food into smaller particles (mastication) Mixes
food with saliva that contain digestive enzymes such as salivary amylase (which helps the breakdown of
