Answer:
The correct answer is: 6 molecules of carbon dioxide are required in order to produce 1 molecule of glucose.
Glucose is synthesized in light-independent phase of the photosynthesis by cyclic process called Calvin cycle.
It takes place in the chloroplast and utilize ATP and NADPH produced in light-dependent phase of the photosynthesis.
Calvin cycle is divided into three parts: carbon fixation, reduction, and regeneration.
The cycle fixes 1 molecule of carbon per rotation. In addition, it requires 3 ATP and 2 NADPH in a single turn.
The cycle turns 6 times to produce one molecule of glucose. Hence, it requires 6 CO₂, 18 ATP, and 12 NADPH to fix one molecule of glucose.
Answer:
Nonsense mutation: it causes a premature stop codon, so the protein cannot be fully synthesized.
Missense mutation: it causes change on the aminoacid encoded, so it can cause a change in the protein structure if the new aminoacid doesn't have the same chemichal properties as the original.
Synonymous (silent) mutation: it causes no change, the same aminoacid is encoded.
Single nucleotide insertion or deletion: changes the entire structure of the protein because it shifts the reading frame.
Three nucleotide deletion: one aminoacid will no longer be part of the protein, if this aminoacid was located, for example, on the active site of an enzyme, the protein could lose its function.
Chromosomal translocation: it can break a gene in two, causing the protein to no longer be able to be synthesized, or it can change the transcription regulation because it is now under the effect of other regulating sites that result in a different transcription pattern.
