Cellular Respiration and Photosynthesis

36 ATP This ATP can now be used
in all cellular processes (Do you remember this from before?) Cellular Respiration reaction So, can humans/animals live without plants (or other photosynthetic organisms)?

ATP (energy), carbon dioxide, and water are all products of the cellular respiration reaction.

Cycle of Photosynthesis and Respiration - VTAide


Glycolysis itself yields two ATP molecules, so it is the first step of anaerobic respiration. , the product of glycolysis, can be used in to produce ethanol and + or for the production of lactate and NAD+. The production of NAD+ is crucial because glycolysis requires it and would cease when its supply was exhausted, resulting in cell death. A general sketch of the anaerobic steps is shown below. It follows Karp's organization.

How do cell respiration and photosynthesis ..

Following photosynthesis, the glucose constructed within plant cells can then be used as a source of energy and materials for cellular activities such as growth, reproduction and the synthesis of more complex materials such as starch, proteins, and fats. The existence of all naturally-occurring molecules (any molecule containing carbon, , and oxygen), and therefore, all sources of energy, can be traced back to the process of photosynthesis. This concept will become very important as we study the flow of energy through ecosystems and the use of energy by humans later in the course.

Photosynthesis and Cell Respiration Assignment

Energy is defined as the ability to do work. The cells of all organisms, and therefore, all organisms, require a continuous supply of energy for the performance of their daily, vital activities. Carbohydrates, especially glucose, generally provide this energy through the process of respiration. Simply stated, respiration is the release of energy from energy-storing compounds. It is represented by the chemical equation:

Power Point 5.1: Cell Energy (Photosynthesis & Respiration)

You should be careful to notice that the process of cellular respiration is essentially the reverse of photosynthesis. The catabolic breakdown (burning) of glucose requires the presence of oxygen and yields energy and . This process is generally the same when any organic molecule is respired (or burned) whether it is glucose in a living animal or plant cell, wood in a fire, or gasoline in a car. The breakdown of any energy storing chemical releases carbon dioxide as a byproduct, which may then be used by plants in the photosynthetic process.
