<span>Enzymes</span> are proteins that allow certain chemical reactions to take place much quicker than the reactions would occur on their own. Enzymes function as catalysts, which means that they speed up the rate at which metabolic processes and reactions occur in living organisms. Usually, the processes or reactions are part of a cycle or pathway, with separate reactions at each step. Each step of a pathway or cycle usually requires a specific enzyme. Without the specific enzyme to catalyze a reaction, the cycle or pathway cannot be completed.

Which statement about the light-independent reactions in photosynthesis is true?.
rjkz [21]

Answer:

The correct answer would be They comprise the Calvin cycle.

Calvin cycle refers to the set of chemical reactions taking place in the stroma of the chloroplast in which carbon is fixed into food (glucose). The whole process is divided into three stages namely: fixation, reduction, and regeneration (ribulose bisphosphate or RuBP).

It takes place in light-independent reaction of the the photosynthesis.

It does not require light energy to carry out the reactions however, it depends upon the products of light reaction (ATP and NADPH).

Fixation of one molecule of glucose requires 6 molecules of carbon dioxide, 9 ATP and 6 NADPH.

The fixation of carbon is catalyzed by an enzyme RuBisCO.

Why is bacteria placed in the kingdom prokaryotes
sukhopar [10]
Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.

Hope this helps! :)
