Textbook Question
Match the following terms with the correct functions.
Peroxisome
Ribosome
Smooth endoplasmic reticulum
Mitochondrion
Golgi apparatus
Lysosome
Rough endoplasmic reticulum
Vesicle
a. Modifies and folds proteins into the correct structure
b. Modifies, packages, and sorts proteins
c. Contains digestive enzymes
d. Granular organelle that makes proteins
e. Synthesizes most of a cell’s ATP
f. Contains enzymes that oxidize toxins and fatty acids
g. Membrane-enclosed structure used to transport substances through the cell
h. Detoxifies certain chemicals, makes lipids, stores calcium ions
Verified step by step guidance1
Step 1: Understand the function of each organelle listed in the problem. For example, peroxisomes contain enzymes that oxidize toxins and fatty acids, while ribosomes are granular organelles responsible for protein synthesis.
Step 2: Match each organelle to its corresponding function based on its role in the cell. For instance, the mitochondrion synthesizes most of a cell's ATP, and the Golgi apparatus modifies, packages, and sorts proteins.
Step 3: Pay attention to the specific keywords in the functions provided. For example, 'digestive enzymes' clearly point to lysosomes, and 'detoxifies certain chemicals, makes lipids, stores calcium ions' aligns with the smooth endoplasmic reticulum.
Step 4: Use the structural and functional characteristics of the organelles to match them accurately. For example, the rough endoplasmic reticulum modifies and folds proteins into the correct structure due to its association with ribosomes.
Step 5: Ensure that the membrane-enclosed structure used to transport substances through the cell is identified as a vesicle, based on its role in cellular transport.

Protein Synthesis and Processing
Protein synthesis is the process by which cells create proteins, essential for various cellular functions. Ribosomes, rough endoplasmic reticulum, and the Golgi apparatus are key players in this process, where proteins are synthesized, modified, and sorted for transport. Recognizing the roles of these structures helps in understanding how proteins are produced and utilized within the cell.
