Conversion of glucose into pyruvate involves two phases requiring the use of enzymes. The first phase requires the intake of energy allowing for the rearrangement of the sugar molecules and the attachment of phosphate on either end of the molecule The unstable molecule, usually fructose-1, 6- bisphosphate formed from glucose splits into two phosphates carrying three carbon sugars.

The second phase involves the release of energy from the sugars formed in the previous steps.

The process releases energy through the electrons moving across the mitochondrial membrane 9. Additionally, it utilizes acetyl coenzyme A CoA a product of the oxidation process of the pyruvate. Acetyl-CoA associates with carbon accepting molecules forming citrate, which is a six-carbon molecule.

Re-arrangement of the molecule releases two of its carbon particles producing carbon dioxide and NADH. The final step in respiration is the movement of charged electrons through the mitochondrial membrane. Consequently, the movement results in attraction of oppositely charged molecules leading to the production of ATP, the primary source of energy.

Effects of Honey on the Respiration Rate of Saccharomyces Cerevisiae Infection Saccharomyces cerevisiae belongs to the yeast family one of the eukaryotic organism.

Yeast absorbs sugar breaking down the molecules into simple sugars such as the monosaccharides and generating the energy-rich ATP.

According to Kwakman, Paulus, and Sebastian, honey comprises of the sugars fructose, glucose, and sucrose. Sucrose is a disaccharide composed of the sugar glucose and fructose. The breaking down of sucrose into glucose involves the enzymes sucrase and isomerase.

Sucrase facilitates the splitting of sucrose into fructose and glucose. Comparatively, enzyme isomerase converts fructose into glucose for respiration The mechanism of the enzyme sucrose involves a process referred to as hydrolysis requiring water to break the chemical bonds.

Acidic conditions enhance the process of hydrolysis separating the hydrogen molecule from the water molecule. The equation below illustrates the process leading to glucose formation. Additionally, there is an increased production of carbon dioxide caused by the breakdown of glucose to release energy.

Although the process begins at a slow rate, it proceeds with a rapid production of carbon dioxide and later reduces to the minimum production of the gas as the products of fermentation increase.

Table1 illustrate the performance of honey about the volume of gas with respect to time. An increase in osmotic concentrations of the sugar reduces the amount of water necessary for the growth of the yeast.

Consequently, increased sugar levels shift the movement of water in the yeast cells. In regards to Bento et al. The characteristic of the process begins with an oxidative phase during the exponential period and increased fermentation towards the end of the phase 3.

Variations in carbon dioxide production with time provide the evidence for the different characteristic of the growth phases of the yeast cells. Additionally, decreased respiration across the exponential growth rate indicates changes in the metabolism process with an increase in fermentation.

The data on honey and the amount of gas volume produce presents a typical example of changes in rate of respiration as metabolism of the sugar proceeds. It is imperative to consider the pH of honey as a factor affecting cellular respiration rate.

Saccharomyces cerevisiae thrives best in an acidic condition within the ranges of 4 to 4.

Automatic Translation

Comparatively, honey contains both organic and amino acids influencing its pH range of 3. Organic acids include acetic, lactic, citric, formic and gluconic acid.

Additionally, it is found to contain aromatic and aliphatic acids.View Saccharomyces cerevisiae Research Papers on srmvision.com for free.
