Lectures 11 and 13: Photophosphoryaltion/ATP production & The Calvin Cycle
The Calvin Cycle: the reduction of CO 2 to Glyceraldehyde 3-Phosphate. Figure 1. Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. In plant cells, the Calvin cycle is located in the chloroplasts.

The main requirement for the photocell or photoreactor is to allow maximum light to reach the PE. This paper presents an overview of the PE configurations and the possible photocell and photoreactor design for hydrogen production by PEC water splitting.
Photosynthesis
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.. The process. …

8.6: The Light-Dependent Reactions of Photosynthesis
The energy released by the hydrogen ion stream allows ATP synthase to attach a third phosphate group to ADP, which forms ATP. This flow of hydrogen ions through ATP synthase is called chemiosmosis because the ions move from an area of high to an area of low concentration through a semi-permeable structure. In cyclic photophosphorylation ...

Cell Energy Cycle
The Cell Energy Cycle Gizmo™ illustrates two processes that are essential to life: photosynthesis and cellular respiration. Although both of these processes involve a series of complex steps, the inputs and outputs of each process are four relatively simple molecules. 1. What is the chemical formula of oxygen?

A "photoelectrochemical cell" is one of two distinct classes of device. The first produces electrical energy similarly to a dye-sensitized photovoltaic cell, which meets the standard definition of a photovoltaic cell. The second is a photoelectrolytic cell, that is, a device which uses light incident on a photosensitizer, semiconductor, or aqueous metal immersed in an electrolytic solution to directly cause a chemical reaction, for example to produce hydrogen via the electrolysis of water.
Metabolism
Metabolism - Energy, Cells, Processes: It is characteristic of catabolic routes that they do not lead to uniquely identifiable end products. The major products of glycolysis and the TCA cycle, for example, are carbon dioxide and water. Within the cell, the concentrations of both are unlikely to vary sufficiently to allow them to serve as effective …
