Answer:
1. Forms part of the subunits for the protein-synthesizing organelle. - Ribosomal RNA.
2. A molecule that binds to a specific codon and specific amino acid simultaneously. - Transfer RNA.
3. Attaches the correct amino acid to its transfer RNA. - Synthetase enzymes.
4. It provides the energy needed for synthesis reactions. - ATP
5. Produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made. - Messenger RNA
6. May be attached to the ER or scattered in the cytoplasm. - Ribosomal RNA.
Important notes:
- Messenger RNA is also written as mRNA
- Transfer RNA is also written as tRNA
- About point number 6:
To be more accurate, it is the whole ribosome that can be attached to the ER or scattered in the cytoplasm. However, because the ribosome is made of proteins <u>and</u> Ribosomal RNA, then <u>it is also true that </u><u><em>Ribosomal RNA can be attached to the ER or scattered in the cytoplasm</em></u><u>.</u> Although "synthetase enzymes" could be another option for this point, it is not accurate to say that synthetase enzymes,<u> in general</u>, could be <em>attached to the ER or scattered in the cytoplasm</em> because <u>there are other synthetase enzymes in other places besides the cytoplasm</u> or the Endoplasmatic Reticulum (ER).
Answer:
Maltose
Explanation:
Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt.
The monosaccharide unit on the left is the hemiacetal of the α-d-glucopyranosyl unit. It is linked by an α-(1,4′) glycosidic bond to β-d-glucopyranose, the aglycone. The oxygen atom of the glycosidic bond is approximately in the center of the structure, between the two rings. It is projected down, axial, and therefore α. It is linked to C-4 of the aglycone, and so the link is axial–equatorial.
Maltose has a more formal, IUPAC of name: 4-O-(α-d-glucopyranosyl)-β-d-glucopyranose. This rather forbidding name is not quite as bad as it looks. The term in parentheses refers to the glucose unit on the left, which contributes the acetal portion of the glycosidic bond. The term -pyrano- tells us that this part of the structure is a six-membered ring, and the suffix -osyl indicates that the ring is linked to a partner by a glycosidic bond. The prefix 4-O- refers to the position of the oxygen atom on the aglycone, the right-hand ring. The term β-d-glucopyranose describes the aglycone.
Because the aglycone is a hemiacetal, maltose undergoes mutarotation. For the same reason maltose is a reducing sugar. The free aldehyde formed by ring opening can react with Benedict’s solution. The acetal part of the structure is called the “nonreducing end” of the disaccharide. If we do not want to specify the configuration of the aglycone, we use the name 4-O-(α-d-glucopyranosyl)-d-glucopyranose.

A. Stomach
Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.
