Could you help me with these
Directions: Either it's a carboyhdrate, lipid, protein, nucleic acid
It's monomers contain NH2 amd COOH groups
Controls cell reproduction and activities
Ratio of hydrogen to oxygen is 2:1
Is held together with peptide bonds
#1 is amino acids.
#3 is H2O
those aren't the choices
which compound has h20?
Sure! I can help you with that.
To determine whether it is a carbohydrate, lipid, protein, or nucleic acid, we can analyze the given characteristics:
1. Monomers with NH2 and COOH groups:
Carbohydrates have monomers called monosaccharides which do not have NH2 and COOH groups. Lipids do not have monomers. Nucleic acids have monomers called nucleotides, which contain a sugar, a phosphate group, and a nitrogenous base. Proteins, on the other hand, have monomers called amino acids, which contain the NH2 (amino) and COOH (carboxyl) groups.
2. Controls cell reproduction and activities:
Carbohydrates and lipids are primarily involved in energy storage and structural support, not in controlling cell reproduction or activities. Proteins, on the other hand, have a wide range of functions in cells, including controlling cell reproduction and activities through enzymes and other regulatory proteins. Nucleic acids are involved in storing and transmitting genetic information, but not primarily in controlling cell activities.
3. Ratio of hydrogen to oxygen is 2:1:
Both carbohydrates and nucleic acids have this ratio, with the molecular formula (CH2O)n representing carbohydrates and various ratios of carbon, hydrogen, oxygen, nitrogen, and phosphorus representing nucleic acids. Lipids can vary in composition and do not typically have this specific ratio. Proteins contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur, but their ratio doesn't follow the 2:1 pattern.
4. Held together with peptide bonds:
Peptide bonds are specific to proteins. They are formed through a process called dehydration synthesis, in which the amino group (-NH2) of one amino acid bonds with the carboxyl group (-COOH) of another amino acid, releasing a water molecule.
Based on these characteristics, the molecule in question is most likely a protein, as it meets all of the given criteria.
