The statements that accurately describe the structure and importance of monosaccharides are:
1. **A monosaccharide is able to pass through the cell membranes of organisms.** - This is true, as monosaccharides, being small molecules, can often pass through cell membranes via facilitated diffusion.
2. **A monosaccharide is a reactant in cellular respiration.** - This is true; monosaccharides, such as glucose, are key reactants in cellular respiration, where they are broken down to provide energy for the cell.
5. **A monosaccharide consists of a single ring structure of carbon, hydrogen, and oxygen.** - This statement is generally true, as monosaccharides can exist in a ring form (cyclic structure), typically with 5 or 6 carbons in that ring structure.
The following statements are not accurate:
2. **Monosaccharides must be combined to form complex carbohydrates to be used by organisms.** - This is false because monosaccharides can be utilized directly for energy; they do not need to be combined to be used by organisms.
4. **A monosaccharide consists of two rings of carbon, hydrogen, and oxygen.** - This is false; monosaccharides consist of a single-ring structure (in a cyclic form) and do not have two rings.
So, the accurate statements are 1, 3, and 5.
