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)
Answer:
Obese
Explanation:
Obesity can occur at any age but in recent times more and more children are becoming obese. They develop an unhealthy relationship with food from a young age. Food rather than being a source of nutrition becomes just a source of sensory stimulation.
These children often chew very fast and swallow food without properly breaking it down. Thus they are not able to realize when they are full. They ignore the internal cues for hunger or fullness and keep eating to satisfy their palate. As a result, they become obese.
Answer:
Alternation of generation with both sexual and asexual
Explanation:
In mosses, the dominant plant is called a gametophyte while in ferm the dominant is sporophyte. Gametes are produced by the gametophyte and fertilization occurs forming an embryo. The embryo develops into a plant called the sporophyte.
Darwin's plans to find out about simulated choice by examining pigeons is that he needed to learn whether you can change the entire species taking after that particular pigeon into another type of pigeons. I hope the answer will help you.
