Summary Introduction

To analyze:

Whether the fungus is able to reproduce, in case if a mutation takes place and the fungus is not able to produce a minus mating type.

Introduction:

Fungi are the eukaryotic species, which comprise both the multicellular and unicellular species in their genera. In fungi, reproduction is a complicated procedure and certain environmental factors play an essential function in the process of reproduction. Reproduction can take place both sexually and asexually on the basis of the existence and non-existence of the adequate environmental conditions.

Explanation of Solution

Mutation refers to the modification in the sequence of nucleotide that changes the genetic composition of the species. It can result in a harmful effect on the functioning individual and may even result in a fatality. In case, if mutation takes place in the fungus and it influences the generation of minus mating type, then the fungus would no longer possess the tendency to reproduce sexually.

However, the fungus would have the tendency to generate offspring with the help of asexual mode of reproduction. This process would incorporate the fungal hyphae to generate spores that upon meiosis will further produce fungal hyphae. The hyphae can also go through the process of fragmentation from which novel colonies can be developed. Apart from these, it can also reproduce asexually by budding.

Conclusion

The life processes of the fungus to reproduce sexually as well as asexually permits the fungus to reproduce, even in the non-existence of sexual reproduction conditions.

If a bacterium using aerobic respiration was to degrade one small protein molecule into 8 molecules of pyruvic acid, how many ATP would that cell make? Assume there is no other carbon source.   Units cannot be entered in this style of question but the units of your answer should be in molecules of ATP.
If a bacterium using aerobic respiration was to degrade a 30 mM solution of citric acid, how many ATP would that cell make?  Assume no other carbon source is available.  Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
How much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid. Recall that when glycerol breaks down to Glyceraldehyde-3-phosphate it costs one ATP but your get an extra FADH2. Every two carbons of a fatty acid break down to one acetyl-CoA. (pathways will be provided on the exam) Units cannot be entered in this style of question but the units of your answer should be in mM of ATP.
