Mitochondria
Multiple Choice
In the context of mitochondria, why do some cells (e.g., skeletal muscle cells) contain more mitochondria than others (e.g., some resting connective tissue cells)?
A
Cells that secrete large amounts of protein contain more mitochondria because mitochondria are the main site of ribosome assembly and protein translation.
B
Cells that synthesize more DNA require more mitochondria because mitochondria are the primary site of DNA replication in eukaryotes.
C
Cells exposed to more sunlight contain more mitochondria because mitochondria perform photosynthesis to generate ATP.
D
Cells with higher ATP demand for sustained activity require greater oxidative phosphorylation capacity, so they contain more mitochondria.
Verified step by step guidance1
Understand the primary function of mitochondria: they are the powerhouse of the cell, responsible for producing ATP through oxidative phosphorylation.
Recognize that different cell types have varying energy demands based on their functions; for example, skeletal muscle cells require a lot of energy for contraction and sustained activity.
Connect the energy demand to mitochondrial number: cells with higher ATP requirements need more mitochondria to meet this demand efficiently.
Note that mitochondria are not involved in ribosome assembly, protein translation, or DNA replication in the nucleus, nor do they perform photosynthesis; these functions are carried out by other cellular components.
Conclude that the reason some cells contain more mitochondria is to increase their capacity for ATP production to support their specific energy needs.
