certain cells have densely packed mitochondria and the cristae ( infolded projections of a mitochondrion) are very closely together. what would you predict about the function of such cells? explain your reasoning

What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.

Explanation:

Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.

A cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high.

An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
