Use this diagram of an animal cell to answer the question. where does the first stage of cellular respiration occur? (a)w(b)x(c)y(d)z

(D) Z

Explanation:

Cellular respiration is a catabolic process by which cells produce energy by oxidising respiratory substrates such as glucose. It is a multistage process occurs in cytoplasm and in mitochondria of a cell. The first stage of cellular respiration is called glycolysis or EMP (Embden, Meyerhof and Parnas) pathway. This stage occurs in the cytoplasm of a cell which is labeled by Z in the given image.
