During muscle contraction, the labeled ATP is observed to attach to the sarcomere
During muscle contraction, ATP (adenosine triphosphate) is utilized to power the cross-bridge cycling between actin and myosin filaments in the sarcomere.
As the myosin heads bind to actin, ATP is hydrolyzed into ADP (adenosine diphosphate) and inorganic phosphate, releasing energy that causes the myosin heads to change conformation and generate force. The released ADP and inorganic phosphate remain bound to the myosin head until a new molecule of ATP binds to it, causing the myosin to detach from actin and reset its conformation. Therefore, while ATP is not directly attached to the sarcomere during muscle contraction, its hydrolysis and subsequent binding to myosin is essential for the contraction process to occur.

This switch from haploid to diploid triggers the cell to start dividing by
The switch from haploid to diploid triggers the cell to start dividing by mitosis. Mitosis is the process of cell division in which one cell divides into two identical daughter cells. This process is essential for growth and repair in multicellular organisms.
When a haploid cell becomes diploid, it means that it has undergone fertilization and its chromosomes have doubled. The newly formed diploid cell then undergoes mitosis to divide and produce more cells.During mitosis, the replicated chromosomes condense and line up at the equator of the cell. The spindle fibers then attach to the chromosomes and pull them apart, ensuring that each daughter cell receives a complete set of chromosomes. The cell then divides into two identical daughter cells.The switch from haploid to diploid triggers the cell to start dividing by mitosis because diploid cells have twice the number of chromosomes as haploid cells. This means that there is more genetic material that needs to be distributed evenly between the daughter cells during cell division. Mitosis is the process that ensures that each daughter cell receives an identical copy of the genetic material. Without mitosis, cells would not be able to divide and grow, and multicellular organisms would not be able to develop or repair damaged tissues.For more such question on mitosis

On secreted glycoproteins, asparagine is joined to N-linked oligosaccharides in the form of Asn-X-Ser/Thr. Here option D is the correct answer.
N-linked oligosaccharides are a type of glycan that is covalently attached to specific asparagine residues on glycoproteins. The attachment of these oligosaccharides occurs through a process called N-glycosylation, which is catalyzed by a complex set of enzymes located in the endoplasmic reticulum and Golgi apparatus.
The specific attachment site for N-linked oligosaccharides is the asparagine residue that is located within a specific amino acid sequence, Asn-X-Ser/Thr, where X can be any amino acid except proline. This sequence is commonly referred to as the N-glycosylation sequon.
During N-glycosylation, a pre-assembled oligosaccharide is transferred en bloc from a lipid carrier to the asparagine residue of the N-glycosylation sequon, forming a glycosidic bond between the N-acetylglucosamine (GlcNAc) residue of the oligosaccharide and the amide nitrogen of the asparagine residue. The oligosaccharide is then further modified by additional glycosylation and processing enzymes as it travels through the secretory pathway.
