Answer:
Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. All live in water, and move by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants.
ATP or Adenosine triphosphate is well know for it's energy source but despite it has many roles in cell. ATP is primarily used as energy source as it has higher energy in it's phospho-di-ester bonds between P and P atoms. It is hydrolyzed to ADP & AMP to give energy.
There are several different processes, including glycolysis and the Calvin Cycle, but the umbrella term for getting energy from glucose is cellular respiration.
the answer supposed to be peptide bonds
The correct option is D. Organisms work best at their optimum temperature and pH, above and below these temperature they will not be able to function as expected. It is possible that the students above use different temperature and pH when they were carrying out their experiments, this will result in different efficiency rate by the yeasts.
