B- Metamorphic rocks. metamorphic rocks are formed through the change of igneous and sedimentary rocks. which sandstone and basalt are. metamorphic rocks are also formed through heat and pressure
Answer:
Thiamine pyrophosphate (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.
Explanation:
Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.
The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.
Not necessarily because cells them self don't actually contain cells
Answer: diplontic plant
Explanation:
The mosses belongs to the phylum of non-vascular plants. They produce spores instead of seeds. They do not produce flowers, true roots and wood. They do not posses a vascular system. They exhibit a diplontic life cycle. The diplontic life cycle involves the formation of diploid gametes. In mosses the diplontic life cycle the mosses produces diploid cells and in only one stage they produce haploid cells.
