Where in a cell are the enzymes involved in the Electron Transport Chain (ETC) and the TriCarboxylic Acid (TCA) cycle found?

✅Explanation:  The enzymes involved in the Electron Transport Chain (ETC) are located in the inner mitochondrial membrane, where they facilitate the transfer of electrons and generation of ATP through oxidative phosphorylation.
 The enzymes of the TriCarboxylic Acid (TCA) cycle, also known as the Krebs cycle, are found in the mitochondrial matrix, where they play a central role in energy metabolism by oxidizing acetyl-CoA to produce NADH, FADH₂, and ATP (or GTP).

📌📌Other Options:
-Ribosomes: Ribosomes are cellular structures in the cytoplasm or rough endoplasmic reticulum (ER) responsible for protein synthesis.
-Endoplasm: The endoplasmic reticulum (ER) is a network of membranes in the cytoplasm. While the rough ER has ribosomes attached for protein synthesis.
-Cytoplasm and nucleus: The cytoplasm is the fluid inside the cell, and the nucleus houses the genetic material (DNA).
