Answer – B (Electrons)
When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.
ATP is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is GTP.

What is GTP?</h3>
- A purine nucleoside triphosphate is guanosine-5'-triphosphate.
- It serves as one of the components necessary for the creation of RNA during transcription.
- The main distinction between its structure and that of the guanosine nucleoside is the presence of phosphates on the ribose sugar of nucleotides like GTP.
- Also known as guanosine triphosphate, this energy-dense nucleotide is similar to ATP and is made up of guanine, ribose, and three phosphate groups.
- It is required for the creation of peptide bonds during protein synthesis.
- Adenine nitrogenous base, sugar ribose, and triphosphate make up ATP, a nucleoside triphosphate, whereas guanine nitrogenous base, sugar ribose, and triphosphate make up GTP.
- This is the main distinction between the two compounds.
- The alpha-guanosine subunit's diphosphate (GDP) is converted into guanosine triphosphate (GTP), and the GTP-bound alpha-subunit subsequently separates from the beta- and gamma-subunits.

Answer: This is a positive feedback loop.
Explanation:
The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.
These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.
The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.
This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.
Oh! Just did this in school!
Eukaryotic cells are more complicated than prokaryotic. Eukaryotic cells have DNA in their nucleus, they have more than one chromosome, lysosomes, preoxysomes, mitochondria, cytoskeleton, golgi apparatus
