This type of regulation is called 37) What the two mechanisms that microorganisms use to generate ATP? 38) (6 pts). What is the similarity and difference of anaerobic respiration and fermentation?

Explanation / Answer

31. Answer:- energy
Explanation:- Potassium uniport is an example of secondary active transport system because it use energy of the proton motive force.

32. Answer:- plasmid
Explanation- Bacteria often contain extra chromosomal DNA molecules called plasmid that replicate independently of chromosomal DNA.

33.Answer:- Autoclace
Explanation- Endospores, due to heat resistance, are the reason for extreme methods of sterilization called Pressurized steam (autoclaving).
- Typical treatment is 121°C/15 psi pressure for 15 minutes, a process that destroys endospores. Heated water -> steam -> increased pressure.

34. Answer:- Endosymbiotic theory
Explanation:- To explain the origin of eukaryotes, Lynn Margulis developed Endosymbiotic theory in which respiring bacterium or phototrophic bacterium was internalized into a pre-eukaryotic cell.

35. Answer:- catabolism and anabolism
Explanation:- There are two parts in metabolism: 1) catabolism are the enzyme-regulated reactions that release energy and building blocks for biosynthesis.
2) anabolism are the enzyme-regulated reactions that build complex organic molecules from simpler ones using energy and building blocks.

36. Answer:- Competitive inhibition
Explanation- in competitive inhibition the final product can competitively inhibit the activity of one of the enzymes earlier in the pathway.

37. Answer:- (a)photo phosphorylation
(b) oxidative phosphorylation

38. Answer:- ANAEROBIC RESPIRATION VS FERMENTATION:-

SIMILARITIES:-
- both occur in the absence of oxygen.
- both produce little amount of ATP.
DIFFERENCE:-
- fermentation is Extracellular process but anaerobic respiration is intracellular.
- in fermentation glycolysis not follow krebs cycle and ETS. But in anaerobic respiration it follow both.
