2. In gluconeogenesis, it takes two enzymes to convert pyruvate to phosphoenolpyruvate. a. Explain what is happening chemically
Marina CMI [18]

Answer:1. Pyruvate carboxylase

2. Phosphoenol pyruvate carboxy kinase

Explanation:

The conversion of pyruvate to phosphoenol pyruvate is catalyzed by two enzymes Pyruvate carboxylase and phosphoenol pyruvate carboxy kinase

1. Pyruvate carboxylase reaction

Pyruvate in the cytoplasm enters the mitochondria. Then, carboxylase of pyruvate to oxaloacetate is catalysed by a mitochondrial enzyme, pyruvate carboxylase. It needs the co-enzymes biotin and ATP.

The oxaloacetate formed has to be transported from the mitochondrial to the cytosol because further reaction of gluconeogenesis are taking place in cytosol.

2. Phoaphoenol pyruvate carboxy kinase (PEPCK)

In the cytoplasm, PEPCK enzyme then converts oxaloacetate to phoaphoenol pyruvate by removing a molecule of CO2. GTP or ITP donates the phosphate group.

The net effect of these two reactions is the conversion of pyruvate to phoaphoenol pyruvate. This circumverts the irreversible step in glycolysis catalyzed by pyruvate kinase (step 9 if glycolysis)

yarga [219]

Answer:Algae contributes to the phosphorus cycle

Explanation:Algae are organisms which have distinct chlorophyll and are autotrophic in nature .Most of them live in water.Algae include the Unicellular chlamydomanas and the multicellular sea weed.some algae are colonial and some are filamentuous.Algae possess chlorophyll, carotenoids and phycobillins as pigments.

Algae are important primary producers in the water bodies and produces a significant portion of oxygen.

Some algae eg diatoms are fossilized due to their glass cell wall and are known as diatomaceous earth, which has various uses such as abrasives,tooth paste and as filters.

Red algae produces calcium carbonate which forms coral reefs.

The products of some algae are used as solid gels and source of agar for microorganism culture.
