(OMG PLEASE HELP ASAP!!:c)What is the major function of proteins in cells? 1.They contain the instructions for the cell to carry out all the functions of life

2.They provide components of cell membranes and organelles and speed up chemical reactions

3.They provide energy and components of cell walls and cell membranes They provide energy and components of cell walls and cell membranes

4.They store energy and provide certain components of cell membranes

1. They contain the instructions for the cell to carry out all the functions of life.

Explanation:

Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
