Answer:
Molecules carrying amino acids are positioned in the ribosome’s two docking sites.
Explanation:
A ribosome is a molecular machine that coordinates protein assembly.
- A ribosome brings together correctly the mRNA, which needs to be translated, and the tRNA, which assists in the translation process, to come together correctly.
- During translation, tRNA molecules carrying amino acids are positioned in the ribosome’s two docking sites.
- After the translation, the tRNA disassemble and is being reused many times.
Excitation-contraction coupling refers to the series of events that begins with the excitation of the sarcolemma in response to stimulation by a neurotransmitter, and results in the release of calcium ions from the sarcoplasmic reticulum.
Hence, option D is the 1st process that starts the excitation-contraction coupling.
