Answer:
Bromelain refers to a collection of proteases containing sulfhydryl groups. Each protease consists of amino acids, which are the fundamental components of proteins.
Explanation:
Bromelain:
It is not classified as a singular enzyme. Instead, it comprises a combination of proteolytic enzymes along with phosphatases, glucosidases, peroxidases, cellulases, and glycoproteins. Initially, bromelain was identified as an enzymatic mix derived from pineapple plants (Ananas comosus), but it is now recognized as any protease sourced from the Bromeliaceae family.
Proteins are large molecules made up of amino acid subunits or monomers. These amino acids, linked by peptide bonds, create the intricate structure of enzymes.
Answer:
Paraquat serves as a herbicide.
Explanation:
Coral bleaching wasn't induced by paraquat since it is a herbicide aimed at eliminating weeds, not algae. Coral hosts small algae essential for its coloration, hence applying paraquat wouldn't affect these algae, thus preventing coral bleaching. In contrast, if a different chemical that targets algae is used, it results in coral bleaching and turns the coral white.
Answer:
The light-independent reactions initiate with carbon dioxide and culminate in glyceraldehyde-3-phosphate (G3P). Energy from ATP and NADPH generated in light-dependent reactions is utilized for this process.
Explanation:
Step 1: Carbon dioxide combines with ribulose biphosphate (RBP) to create a six-carbon sugar, which quickly breaks down into two molecules of 3-phosphoglycerate (3-PGA).
CO₂ + RBP ⟶ 2 3-PGA
Step 2. A phosphate group is added to 3-PGA, forming 1,3-bisphosphoglycerate (1,3-BPG).
3-PGA + ATP ⟶ 1,3-BPG + ADP
Step 3. NADPH facilitates the reduction of 1,3-BPG to G3P.
1,3-BPG + NADPH ⟶ G3P + NADP⁺
Most of the G3P is converted back into RBP, although some exits the cycle to form glucose.

The claim that the TYR, TRP2, and TRP1 genes are located adjacent to one another on a single chromosome and arranged into an operon is likely accurate.
Choice a is the right answer.
Explanation:
The genes responsible for Tyrosinase, TRP2, and TRP1 can be found on the same chromosome and form an operon. They act as an operon because their regulation is handled by identical transcription factors on mRNA.
The Tyrosinase enzyme plays a crucial role in producing melanin, eye colors, and hair pigmentation. The formation of these components transpires through three distinct reactions facilitated by TRP1, TRP2, and Tyr genes, which function as an operon with protein products that are nearly 40% identical among the three genes.
The melanin production rate hinges on the enzyme activity of all three genes.
Regulation of these genes is executed by operons.
