Verified step by step guidance

Understand the context: Sperm motility refers to the ability of sperm cells to move effectively, which is crucial for their function in fertilization. Motility is powered by energy and structural components.
Identify the key components required for motility: Energy is provided by ATP (adenosine triphosphate), which is the universal energy currency of the cell. ATP is produced by mitochondria through cellular respiration.
Recognize the structural component: The flagellum is the whip-like tail of the sperm that propels it forward. A functional flagellum is essential for movement, as it generates the necessary force for motility.
Eliminate incorrect options: Cholesterol synthesis and lysosome activity are not directly related to sperm motility. DNA replication and spindle formation are processes involved in cell division, not motility. Mitochondrial DNA and ribosome production are important for cellular function but do not directly contribute to motility.
Conclude the essential factors: ATP provides the energy required for movement, and the functional flagellum acts as the structural mechanism for propulsion. These two factors are critical for sperm motility during cell division.
