Question

Question 4 and question 5 Question 4 (1 point) Functions of proteins in cells include stiff filaments that help define a cells shape and hold organelles in place (the cytoskeleton) enzymes that catalyze reactions. molecular signals that enable cells to coordinate and communicate. pores and channels through the plasma membrane through which ions and small molecules can enter and exit the cell Save Question 5 (1 point) We can think of proteins as analogous to words in English, with amino acids as the letters. with nucleotides as the letters. and the order of the letters in the word (or the amino acids in the protein) can change the meaning of the word (or the structure of the protein).

Explanation / Answer

Q4. All these options are correct as

A. It means cytoskeleton. We know that cytoskeleton is made up of actin filaments.

B. Enzymes are proteins

D. Proteins form channels also

THIS IS NOT CORRECT AS

C. MOLECULAR SIGNALS ARE NOT ALWAYS PROTEINS... FEW HORMONES ARE PROTEINS BUT THEY ACT OUTSIDE THE CELLS

Q5. THIS HAS TWO CORRECT OPTIONS-

A. WITH AMINO ACIDS AS LETTERS.... AS PROTEINS ARE MADE UP OF AMINO ACIDS

C. THE ORDER OF LETTERS IN THE WORD CAN CHANGE THE MEANING OF THE WORD...... iT'S correct as as sequence of amino acid change structure and function of protein change...
