Yeast fermentation produces ethanol and carbon dioxide.

  • Fermentation is an anaerobic pathway that breaks down glucose in absence of oxygen.

  • Conversely, cellular respiration requires oxygen to break down glucose molecules.

  • Fermentation is energetically less efficient than cellular respiration in terms of the generation of energy (ATP).

In conclusion, yeast fermentation produces ethanol and carbon dioxide.

pav-90 [236]

Answer:

D) It would contain less nitrogen.

Explanation:

In an investigation of the cycling of environmental gases, a  student placed water and bromthymol blue in each of four test  tubes as shown in the diagrams below. No additional items were  placed in tube 1, a snail was placed in tube 2, an aquatic plant  (elodea) was placed in tube 3, and both a snail and an elodea  were placed in tube 4. The tubes were then stoppered and placed  in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.

The dfferent tubes are shown in the picture that I uploaded.

Which process is catalyzed by rubisco during the light-independent reactions of photosynthesis?
Mekhanik [1.2K]

The right answer is B.carbon fixation.

Rubisco, by its full name ribulose-1,5-bisphosphate carboxylase / oxygenase, is the key enzyme for the fixation of carbon dioxide CO2 in plant biomass by initiating the Calvin cycle, in relation to the solar energy captured. by the chlorophyll at the origin of the processes of photosynthesis. It catalyzes both carboxylation and oxidation of ribulose-1,5-bisphosphate.
