The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...
Student's t-test, Analysis of variance, Mann–Whitney U test Repeated measures design A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods.
Photosynthesis measurement systems are not designed to directly measure the amount of light the leaf absorbs, but analysis of chlorophyll fluorescence, P700- and P515-absorbance, and gas exchange measurements reveal detailed information about, e.g., the photosystems, quantum efficiency and the CO 2 assimilation rates.
The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)
The collective goal is to contribute excellent biology diagrams to the Commons and to corresponding Wikipedia articles. This is done as part of an Advanced Placement Biology course. The lead editor is Chris Packard. This project is inspired by the 2009 Wikipedia AP Biology Project. There are many basic and important diagrams missing from ...
The RIPE project's proof-of-concept study established photosynthesis can be improved to increase yields, [11] published in Science. [12] The Guardian named this discovery one of the 12 key science moments of 2016. [13] Computer model simulations identify strategies to improve the basic underlying mechanisms of photosynthesis and increase yield ...
The 2030 World Cup also will be awarded to a six-nation, three-continent project led by co-hosts Spain, Portugal Morocco. It gives a single game each at South American neighbors Argentina ...
In 2000 it was discovered that if C. reinhardtii algae are deprived of sulfur they will switch from the production of oxygen, as in normal photosynthesis, to the production of hydrogen. [15] [16] [17] Green algae express [FeFe] hydrogenases, being some of them considered the most efficient hydrogenases with turnover rates superior to 10 4 s −1.
