What is true about the function of the electron transport system (ETS)?

Biology
2 answers:
FrozenT [24]3 years ago

The correct answer is the last option.

The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.

The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.

The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.

The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.

garik1379 [7]

Answer:

Co-dominance because he expresses both of the alleles simultaneously

Explanation:

The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.

This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
