1. How are ADP and ATP related? A. ADP contains the sugar ribose; ATP does not B. They are identical except ADP has more energy C. ATP has more phosphate group and more stored energy than ADP. D. ADP has one more phosphate group and more stored energy than ATP 2. What are pigments? A. Pigments are chemical compounds that absorb particular wavelengths of light, and so appear that color to our eyes. B. Pigments are chemical compounds that reflect particular wavelengths of light, and so appear that color to our eyes. C. Pigments are a form of chlorophyll used in the process of photosynthesis D. Pigments consist of all the colors of the rainbow 3. Thinking about photosynthetic pigments, which statement is correct? A. The pigments found within most types of photosynthesizing cells are primarily chlorophylls and carotenoids. B. The pigments that reflect solar energy are in the membrane of the thylakoid C. Pigments play an important role in the absorption of chemical energy for photosynthesis. D. Leaves contain only one type of pigment and that is the green chlorophyll.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
