Games are excellent teaching tools for self-learning. Students playing a game enjoy themselves and at the same time learn basic important concepts. Different games including crossword puzzles, word search knight’s tour games, connecting dots, mazes, matching two sets, amidakuji, logic were used continuous assessment during confinement due to pandemic. These developed as part of GINDO-UB180 inno...

The oxidation of acetic acid in the dark by the non-sulfur purple bacterium, Rhodospirillum rubrum, was shown by van Niel (1, 2) to require the presence of either carbon dioxide or trace amounts of the Cb-dicarboxylic acids of the Krebs cycle. These results could readily be interpreted to mean that the oxidation of acetic acid proceeds by way of the Krebs cycle, the presence of COZ being requir...

Hans Krebs’ discovery, in 1932. of the urea cycle was o major event in biochemistry. This article describes a program, KEKADA, which models the heuristics Hans Krebs used in this discovery. KEKADA reacts to surprises, formulates explanotions, ond carries out experiments in the same manner as the evidence in the form of loboratory notebooks and Interviews indicates Hans Krebs did. Furthermore, w...

Enzymatic analyses of Bacillus thuringiensis extracts suggest that a modified Krebs tricarboxylic acid cycle (without alpha-ketoglutarate dehydrogenase) can operate during sporulation in conjunction with the glyoxylic acid cycle and the gamma-aminobutyric acid pathway.

Homogenates of early chick embryos and homogenates of early chick embryonic hearts utilized the phosphogluconate pathway of glucose catabolism to a greater extent, relative to the glycolytic-Krebs cycle pathway, than did homogenates of hearts from older chick embryos or adult chicks. An abrupt drop in the relative participation by the phosphogluconate pathway in embryo heart homogenates occurs ...
