What is the primary function of the mitochondria in a cell?
to generate chemical energy in the form of adenosine triphosphate (ATP) to power the cell's biochemical reactions
Cell

Prokaryotic DNA is typically structured as:
B) A single, circular chromosome located in the nucleoid region
B) Antonie van Leeuwenhoek
tWhat is the main difference between prokaryotic and eukaryotic cells?
eukaryotic cells have a membrane-bound nucleus and specialized organelles, while prokaryotic cells lack a nucleus and membrane-bound organelles
Why are mitochondria often referred to as the "powerhouses of the cell"?
they generate the vast majority of the cell's supply of ATP (adenosine triphosphate)
Nucleus

What are cristae, and why is their folded structure important?
Cristae are the intricate folds and invaginations of the inner mitochondrial membrane that project inward toward the central matrix
