a. Carbon dioxide is reduced to glucose. b. Chloroplasts convert solar energy to ADP. c. Hydrogen atoms reduce water to glucose. d. Water is hydrolyzed. The oxidized and reduced forms of the electron carrier used in ph...
We also observed a positive linear relationship between the rates of MG production and O2 evolution (R = 0.88; P < 0.0001). These data provide evidence that MG is produced by the Calvin cycle and that sugar-derived RC production is inevitable during photosynthesis. Furthermore, we found that...
The activities of three Calvin cycle enzymes, RuBPc (E.C. 4.1.1.39), 3PGA phosphokinase (E.C. 2.7.2.3) and NADP-G3P dehydrogenase (E.C. 1.2.1.13), and the cytoplasmic enzyme PEPc (E.C. 4.1.1.31) together with soluble protein and chlorophyll were measured in extracts from young toma...
NADPH-dependent thioredoxin reductase C (NTRC) is a chloroplast redox regulator in algae and plants. Here, we used site-specific mutation analyses of the thioredoxin domain active site of NTRC in the green alga Chlamydomonas reinhardtii to show that NTRC mediates cold tolerance in a redox-dependent...

Which step of cellular respiration produces the most ATP per molecule of glucose? A) NADH is oxidized by the electron transport chain. B) FADH_2 is oxidized by the electron transport chain. C) Glucose is reduced to pyruvate. D) Succiny...
Phaeodactylum tricornutum is a unicellular diatom in the class Bacillariophyceae. The full genome has been sequenced (<30 Mb), and approximately 20 to 30% triacylglyceride (TAG) accumulation on a dry cell basis has been reported under different gro
The female megagametophyte, which provides the zygotic embryo with nitrogen (N), carbon (C) and energy during germination, is not present in Norway spruce (Picea abies) mature somatic embryos. Therefore, somatic embryos presumably rely on nutrients supplied in the germination medium in addition to...
Which step of photosynthesis can occur during the presence or absence of light? a. glycolysis b. C3 c. the light reactions d. the Calvin cycle Photosynthesis: It is the process of generation of organic compounds from inorgan...
Glycolysis is a mechanism where one glucose molecule is converted into 2 pyruvate molecules, 2 NADH and net 2 ATP. This process is common in nearly all living organisms, and is very important for many metabolisms. In ...
