Photosynthesis
Photosynthesis sustains virtually all life on planet Earth providing the oxygen we breathe and the food we eat; it forms the basis of global food chains and meets the majority of humankind's current energy needs through fossilized photosynthetic fuels. The process of photosynthesis in plants is based on two reactions that are carried out by separate parts of the chloroplast. The light reactions...
متن کاملTopical Reviews on Photosynthesis Improvement Improving Photosynthesis
Photosynthesis is the basis of plant growth, and improving photosynthesis can contribute toward greater food security in the coming decades as world population increases. Multiple targets have been identified that could be manipulated to increase crop photosynthesis. The most important target is Rubisco because it catalyses both carboxylation and oxygenation reactions and the majority of respon...

voluntarily herd shoals of fish towards fishing boats. The fishermen benefit from enhanced catches and the dolphins feed on the entrapped fish, as well as getting some rewards from the fishermen. Nonetheless, numbers of dolphins have declined in Myanmar as a result of electrocution through illegal electric fishing, entanglement in nets, mercury poisoning and habitat loss from gold mining.

متن کاملC4 photosynthesis
The question then is how the same neurons convey two different sorts of information. The answer is that motor giants are capable of generating two types of action potentials, small/slow calcium spikes and large/fast sodium spikes, depending on the degree of depolarization it receives. As opposed to the input from the ring giant, the input from the pacemaker is too low to trigger the sodium spik...
متن کاملFiring Hot, Firing Cold: How Poikilotherms Compensate for Temperature Swings
If you are reading this, you have one less problem than the crabs that are the subject of a new study in this issue of PLoS Biology. Humans, like all mammals (as well as birds), are ‘‘warm-blooded,’’ or more correctly ‘‘homeothermic,’’ meaning we maintain our core body organs at a constant temperature. We expend considerable energy to do so, and may die when we cannot. In contrast, crabs, cod, ...
