Chemical analysis of mitochondria indicates that these organelles are found within cell nuclei ос do not contain enzymes transport hemoglobin contain ATP molecules

The correct answer is ''contain ATP molecules.''

Explanation:

Energy is produced through a series of chemical reactions coupled to a chain of transport of electrons to oxygen, transforming the energy that is generated into ATP these reactions are carried out thanks to the joint action of a series of proteins and other substances that transport electrons that are located in the inner membrane of the mitochondria and that constitute the oxidative phosphorylation system. The functions of the mitochondria were limited to some metabolic pathways, such as the respiratory chain - that is, the series of biochemical reactions that release the necessary energy to synthesize adenosine triphosphate, or ATP–, oxidative phosphorylation –the synthesis of the ATP molecule– and thermogenesis, which is the extra generation of heat in adipose tissue called 'brown'. The ATP molecule, due to its chemical structure, constitutes the main energy reserve available to the cell to carry out its functions.
