(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.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
