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)
The answer is true. They cannot only replicate themselves within cells, but they cannot outside of a cell.

1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
