Whether temperature effects respiration

To start off this experiment I feel that it is suitable to explain the main facts of this study. Below is a section explaining respiration and aerobic respiration in detail.

Respiration, chemical and physical processes by which animals and plants obtain oxygen and use it to release energy from food molecules. Respiration provides the necessary energy for carrying on all essential life processes.

Respiration is divided into two distinct phases: external respiration and internal, or cellular, respiration. External respiration includes all steps in the process of delivering oxygen to each cell in the body and disposing of carbon dioxide, a gas given off as a waste product when cells use oxygen. In humans and other animals that have lungs, breathing is an essential part of external respiration.

Internal respiration occurs inside every living cell and involves a series of chemical reactions that liberate energy from food. Some of the energy is transformed into body heat while the rest is used to drive other chemical processes that keep the body working. During internal respiration in animals, food molecules are usually combined with oxygen and carbon dioxide is usually released. The experiment that I will conduct is described as aerobic respiration.

The word equation for aerobic respiration is:

Glucose + Oxygen Carbon dioxide + Water + Energy

Aerobic Respiration

The primary method of processing energy for almost all plants and animals is aerobic respiration. In this type of respiration, food molecules are gradually processed into carbon dioxide and water, and large quantities of energy are produced. Some of this energy produces heat, but most of it is stored in molecules of adenosine triphosphate (ATP). When the stored energy is needed, ATP is quickly processed and the energy is made available for use by the body.

The first step in aerobic respiration occurs in the cytoplasm of the cell and involves breaking down glucose. Each glucose molecule is made up of six carbon atoms plus hydrogen and oxygen. When the glucose molecule splits, two pyruvic acid molecules form, each of which contains three carbon atoms. These reactions result in the formation of two molecules of ATP. Some hydrogen is also released in the process.

In the second step, pyruvic acid passes from the cytoplasm into tiny cellular structures called mitochondria, where the remaining reactions occur. Within the mitochondria each pyruvic acid molecule combines with a ...
