Answer:

(d). Sending signals across the organism

Explanation:

Proteins are one of the most important biomolecules that play different roles in organisms. Proteins are made up of polymerization of amino acids. There are some protein molecules that act as signaling molecules that transfer signals from one cell to another.

Insulin hormone, cytokines, and some other peptide hormones are examples of protein molecules that send signals across the organisms.

Thus, the correct answer is option). d.

Answer:

C) protein possesses a signal for localization within the Golgi apparatus.

Explanation:

Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.

Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.

4. Which of the following statements best describes how the traits of an organism are determined

butalik [34]

Answer Choices:

DNA provides the energy needed for an organism to grow and function

DNA is copied into mRNA, which controls cellular functions

DNA codes for proteins, which allow an organism to grow and function

DNA unzips and each strand codes for a different amino acid

Answer:

DNA codes for proteins, which allow an organism to grow and function

Explanation:

DNA provides the energy needed for an organism to grow and function - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.

DNA is copied into mRNA, which controls cellular functions - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.

DNA codes for proteins, which allow an organism to grow and function - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>

DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid

What type of molecule makes up most of the cell membrane?

NikAS [45]

Answer:

Proteins and phospholipids make up most of the membrane structure. The phospholipids make the basic bag, while the proteins are found around the holes and help move molecules in and out of the cell.
