The difference between the glycolysis reaction catalyzed by GAPDH from T. tenax and by E. coli is that the catalysis by T. tenax forms 3-phosphoglycerate instead of 1, 3-bisphophoglycerate (formed by E. coli catalysis).
Glycolysis is the process of cellular respiration which is common in both aerobic as well as anaerobic organisms. It occurs in the cytoplasm of cell. In glycolysis, breakdown of glucose occurs to form 2 molecules of pyruvate.
GAPDH is the short form for the enzyme Glyceraldehyde-3-Phosphate Dehydrogenase. It is involved in catalyzing the a reaction in glycolysis. The reaction involves the simultaneous phosphorylation and oxidation of glyceraldehyde-3-phosphate to 1,3-biphosphoglycerate.

Because its the first step ti a gene expression.
Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein. The human body contains many transcription factors.
Take in- photosynthesis
Return- respiration
Plants takes in carbon during photosynthesis while animals return carbon into the atmosphere during respiration.
Answer and Explanation:
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
- During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
- During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
- G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
