A molecule that contains all the information a cell needs to make protein:
a) ATP
b) carbohydrate
c) lipid
d) protein
e) philosophic
f) nucleic acid
carbohydrates
The correct answer is f) nucleic acid. Nucleic acids, specifically DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), contain the genetic information that cells need to make protein. These nucleic acids are composed of a sequence of building blocks called nucleotides, which consist of a sugar (deoxyribose in DNA and ribose in RNA), a phosphate group, and a nitrogenous base (adenine, thymine/uracil, cytosine, and guanine).
To arrive at this answer, you can recall some basic knowledge about cell biology or use deductive reasoning. Start by understanding that proteins are synthesized in cells based on the information stored in the DNA. Then review the options provided:
a) ATP (adenosine triphosphate) is an energy-carrying molecule, not directly involved in protein synthesis.
b) Carbohydrates are an essential source of energy for cells, but they do not contain the information needed for protein synthesis.
c) Lipids are molecules that serve as structural components of cell membranes or as energy storage, but they do not contain the necessary genetic information.
d) Proteins are the end product of protein synthesis in cells, so they do not contain the information themselves.
e) "Philosophic" is not a scientific term and does not relate to the question.
By process of elimination, you can determine that f) nucleic acid is the correct answer.
