Quizplus · Accepted Answer

Cells contain many different types of proteins that carry out various cellular functions, such as enzymatic activity, structural support, and signaling. Proteins are the main workhorses of cells, performing many necessary tasks for the survival and function of the organism. Zygotes are cells that form during fertilization and develop into embryos, but they are not responsible for the ongoing work of cells.
