BODY ENERGY

Cellular RespirationTask 1

Introduction We get energy from the food that we eat

and the oxygen that we breathe. The food that we eat like carbohydrate,

fats, proteins, vitamins and mineral is all digested and converted to a simple form: Glucose

Glucose is like a type of sugar that provide the body with energy.

Formula

Glucose + Oxygen = Carbon Dioxide + Water + Energy

Cell and Krebs Cycle

The arteriole takes the glucose and oxygen to every cell. Convert to energy. Then it gives carbon dioxide and water to the veinule.

Krebs cycle or (TCA) cycle, is a series of chemical reactions in the cell that breaks down food molecules into carbon dioxide, water, and energy. In plants and animals, these reactions take place in the mitochondria of the cell as part of cellular respiration.

Glycolysis Glycolysis is the name given to the series of

biochemical reactions in which glucose is converted into pyruvate. This important part of carbohydrate catabolism takes place in the cytoplasm of cells.

Measuring Respiration in Living

ThingsTask 2

Human Respiration

The average human breathes 25 times per minute while at rest. Human respiration is controlled by the same part of the brain that controls heart rate. When you are sick or not feeling well, the human respiration rate will change.

The rate of respiration is the number of breaths per minute.

Plant Respiration To measure the respiration of a plant you

have to take a plant and put it in a beaker. Then you will add NaOH to the beaker and the pH will change.

You can calculate the measure of respiration by measuring the volume of NaOH needed to neutralize the pH (carbonic acid).

Animal Respiration

You can measure the rate of respiration for an animal by putting the animal in a sealed box but there has to be something like a hole for the animal to breathe. Then the animal calms down and you can get the numbers.

Exchange of GasesTask 3

The Process of Gas Exchange

We breath in oxygen then it travels through the respiratory system ending to alveoli. Oxygen passes through the blood stream by using capillaries as a place to swap with carbon dioxide so that the alveoli gets the oxygen. Then the carbon dioxide leaves the body when we exhale.
