Oocyte quality and early embryonic development depend
heavily on energy metabolism. Mitochondria are the primary source of ATP in
oocytes and early embryos, supporting processes such as chromosome segregation,
organelle reorganization, and fertilization.

Which pattern of mitochondrial function would
best explain why mitochondria are critical for oocyte competence and early embryonic
development?

Accepted Answer

Mitochondria
produce sufficient ATP to meet the high energy demands of fertilization and
early embryogenesis, supporting cell division and developmental processes

Answer

Mitochondria
primarily use glycolysis rather than oxidative phosphorylation to generate ATP
in oocytes

Answer

Older
oocytes have more mitochondria than younger ones, which compensates for reduced
mitochondrial function with age

Answer

Fertilization
increases Mg²⁺ levels, which alone is sufficient to restore oocyte mitochondrial
function regardless of mitochondrial number or health
