Hello, I am looking for someone to write an article on Biology Assignments. It needs to be at least 1500 words. In experiment C, the yeast was incubated with sucrose, a disaccharide that must be broken into glucose and fructose first. Yeast cells possess the invertase enzyme that s used to break down sucrose into fructose and glucose. This often takes place outside the yeast cell. The yeast then consumes the glucose first followed by fructose. The resultant curve is comparable to that of glucose through glycolysis takes place at a slightly slower rate.

There was no fermentation in experiment D and, therefore, the curve did not form. The primary reason for that is because Saccharomyces cerevisiae does not produce the enzyme required to break down starch. Some fungal species possess alpha-Amylase, an enzyme that can break down starch into simpler sugars (Yeast Fermentation with Different Carbohydrates, par. 2).

In experiment D, the student added amylase to the yeast and starch suspension. Amylase acts on long starch chains, breaking them into maltose and maltotriose. Unlike in experiment C, the amylase added to experiment D was able to break down the starch into simpler sugars that can be digested by Saccharomyces cerevisiae. The resultant curve has a longer log phase which lasts for about 10 minutes. This is the time taken for amylase to break down sufficient amounts of starch for fermentation to begin. The curve does not attain the same levels as that of glucose (Ethanol production by yeast fermentation: Experimental concept,4).

c. A very small fraction of the sunlight energy is used for photosynthesis by the phytoplankton because optimal solar radiation is required for photosynthesis, and not all solar radiation is within the required wavelength (Boyce, Lewis and Warm 592). The radiation from the sun is also too much for photosynthesis and must be dissipated to avoid causing damage to the photosynthetic apparatus. Excess energy from incoming sunlight is lost through reflection and heat.

a. Alfred is Xb Y because he has suffered from vision&nbsp.deficiency which requires the recessive alleles to be expressed phenotypically. Furthermore, the condition is inherited by Keith (second-generation offspring). This implies that he contributed a recessive allele that combined with another recessive allele in the 2nd generation parents to lead to the phenotypic expression of the condition in Keith.
