Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).

photosynthesis | Importance, Process, & Reactions - Proteins

Plants cells contain a number of structures that are involved in the process of photosynthesis:

Enzymes and protein complexes needed in photosynthesis

At temperatures over 40oC enzymes involved in the process are increasingly destroyed, so photosynthesis slows down and eventually stops because the photosynthesis enzymes are destroyed.

Whats the point? So what, we can make mathmatical models of enzyme reactions driving photosynthesis. Why do you think we should care about all of this? (If you are having trouble I suggest you take a deep breath!)

In photosynthetic organisms, the light energy drives the of . Much of the energy is used to reduce the coenzyme NADP+ to form , thereby raising it to a higher energy state. The energy of NADPH is then used in the as a part of the process of carbohydrate synthesis.

These intermediates are characterized by their resistance to so that they can operate in higher temperatures and dryer environments than . At right, the ranges of CO2 compensation points for the three types of plants are shown. These compensation points are the values at which the plants cease to provide net photosynthesis.

The drawback to C4 photosynthesis is the extra energy in the form of that is used to pump the 4-carbon acids to the bundle sheath cell and the pumping of the 3-carbon compound back to the mesophyll cell for conversion to PEP. This loss to the system is why C3 plants will outperform C4 plants if there is a lot of water and sun. The C4 plants make some of that energy back in the fact that the rubisco is optimally used and the plant has to spend less energy synthesizing rubisco.

Lack of chlorophyll/chloroplasts in the plant cells reduce the plant's capacity to photosynthesise.

C4 plants almost never saturate with light and under hot, dry conditions much outperform . They use a two-stage process were CO2 is fixed in thin-walled mesophyll cells to form a 4-carbon intermediate, typically malate (malic acid). The reaction involves phosphoenol pyruvate () which fixes CO2 in a reaction catalyzed by PEP-carboxylate. It forms oxaloacetic acid (OAA) which is quickly converted to malic acid. The 4-carbon acid is actively pumped across the cell membrane into a thick-walled bundle sheath cell where it is split to CO2 and a 3-carbon compound.

even the meat we eat, high in protein and fat, did depend at some point on photosynthesis, so there is no getting away from photosynthesis!

Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

The following steps walk you through the photosynthesis process that occurs each time the sun’s light reaches the leaves of a plant:

BBC - GCSE Bitesize: Photosynthesis

Moore, et al. point to Flaveria (Asteraceae), Panicum (Poaceae) and Alternanthera (Amarantheceae) as genera that contain species that are intermediates between C3 and C4 photosynthesis. These plants have intermediate leaf anatomies that contain bundle sheath cells that are less distinct and developed than the .
