Answer:
Pachytene of prophase I of meiosis I
Explanation:
Crossing over is the process of exchange of genetic material between non-sister chromatids of homologous chromosomes. It occurs during the pachytene stage of prophase I of meiosis I. During pachytene, the paired homologous chromosomes exchange genetic material between themselves and add new gene combinations to the daughter cells.
Cellular respiration releases energy by breaking down glucose in a process that produces ATP. This ATP is used by cells for many functions.
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, the Krebs cycle, and electron transport chain. In these stages, glucose and oxygen are converted into water, carbon dioxide, and energy.
The energy released during this process is used to synthesize Adenosine triphosphate (ATP), which is used by cells for various functions. So, the significant output of cellular respiration is ATP, the central energy currency of cells.
