Question

cytochromes: convert pyruvate to a two - carbon acyl compound. are important metabolic intermediates in the krebs cycle. hydrolyze atp in the energy investment phase of glycolysis. are another reason why you need iron in your diet. are only found in liver cells (hepatocytes).

Explanation:

Cytochromes are proteins that contain iron - containing heme groups. Iron is an essential mineral in the diet as it is required for the synthesis and function of these proteins.

• Converting pyruvate to a two - carbon acyl compound is the function of pyruvate dehydrogenase complex, not cytochromes.
• Metabolic intermediates in the Krebs cycle are molecules like citrate, isocitrate etc., not cytochromes.
• Hydrolyzing ATP in the energy investment phase of glycolysis is done by enzymes like hexokinase and phosphofructokinase - 1, not cytochromes.
• Cytochromes are not only found in liver cells but also in many other cells that carry out aerobic respiration (e.g., muscle cells, neurons etc.) as they are part of the electron transport chain.

Answer:

are another reason why you need iron in your diet.
