Which organic macromolecule is correctly paired with its primary cellular function? A. Nucleic acid -packages materials for export B. Lipid-directs protein synthesis C. Carbohydrate-stores and transmits genetic information D. Protein-provides structural support

## Step 1<br />The problem is asking us to identify the correct pairing of an organic macromolecule with its primary cellular function. The options provided are:<br />A. Nucleic acid - packages materials for export<br />B. Lipid - directs protein synthesis<br />C. Carbohydrate - stores and transmits genetic information<br />D. Protein - provides structural support<br /><br />## Step 2<br />We need to evaluate each option based on the known functions of these macromolecules.<br /><br />## Step 3<br />Option A: Nucleic acid is known for storing and transmitting genetic information, not for packaging materials for export.<br /><br />## Step 4<br />Option B: Lipids are primarily used for energy storage and as structural components of cell membranes, not for directing protein synthesis.<br /><br />## Step 5<br />Option C: Carbohydrates are primarily used for energy storage and as structural components of cell walls, not for storing and transmitting genetic information.<br /><br />## Step 6<br />Option D: Proteins are known for their role in providing structural support to cells, among other functions.
