Cellular Respiration and Photosynthesis: Energy Processes
Cellular Respiration: Stages and Significance
Aerobic respiration, mediated by the aerobic cell, covers the transformation of pyruvic acid into acetyl-CoA, the Krebs cycle, the electron transport chain, and oxidative phosphorylation. Pyruvic acid from glycolysis is completely oxidized to CO2 and water, but little use is made of O2 as the final electron acceptor.
Stages of Aerobic Respiration
- Transformation of pyruvic acid into acetyl-CoA: This is an oxidative decarboxylation catalyzed by a multienzyme

Understanding the Views of an Object
The main view of an object is obtained through orthogonal projections onto six planes arranged in a cube. We can define views as the orthogonal projections of an object according to the different directions from which it is observed.
Title of the Views
If we place an observer according to the six directions indicated by the arrows, we obtain six possible views of an object:
- View A: Front view or elevation
- View B: Top view or plan
- View C: Right side view or right lateral
