To answer the first question, we need to understand where ATP synthase is located. Here are the options:

A. Nucleus
B. Cell membrane
C. Mitochondrial membrane
D. Mitochondrial matrix

To determine the correct answer, we can eliminate options based on our knowledge about where ATP synthase is typically found. ATP synthase is an enzyme involved in cellular respiration, specifically in the production of ATP (adenosine triphosphate) within the mitochondria. Therefore, we can eliminate option A (nucleus) and option B (cell membrane) since they are not connected to the mitochondria.

This leaves us with options C (mitochondrial membrane) and D (mitochondrial matrix). The mitochondrial membrane refers to the double membrane that surrounds the mitochondria, while the mitochondrial matrix is the innermost compartment of the mitochondria.

The correct answer is therefore option D. ATP synthase is located in the mitochondrial matrix.

Now let's move on to the second question:

Each codon on a(n) ____ molecule encodes for ___ amino acids.

A. mRNA...one
B. mRNA...three
C. tRNA...three
D. tRNA...one

To determine the correct answer, we need to understand the roles of mRNA and tRNA in protein synthesis. mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes, where protein synthesis occurs. On the other hand, tRNA (transfer RNA) brings specific amino acids to the ribosomes based on the codons on the mRNA.

A codon is a sequence of three nucleotides on the mRNA that corresponds to a specific amino acid. Knowing this, we can eliminate options A and C, as they state that each codon encodes for one amino acid. Since each codon consists of three nucleotides, it encodes for more than one amino acid.

This leaves us with options B and D. The correct answer is option B, as it states that each codon on an mRNA molecule encodes for three amino acids. Each codon represents a specific amino acid, and since there are 20 different amino acids used in protein synthesis, multiple codons can code for the same amino acid.
