Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
The process of circular motion in the Earth's mantle that causes the plates of the lithosphere to move is called convection.
The answer is B. convection

Conversion of pyruvate to phosphoenolpyruvate (PEP) is bypassed in gluconeogenesis by using two enzymes.
<h3>How does the conversion of pyruvate to phosphoenolpyruvate take place?</h3>
Pyruvate carboxylase and phosphoenolpyruvate carboxykinase (PEPCK) are two different enzymes that work together to catalyze a two-step process that bypasses the glycolytic stage mediated by pyruvate kinase.
The common metabolite of these enzymes is oxaloacetate.
The steps to convert pyruvate to phosphoenolpyruvate are as follows:
- In the mitochondrion, pyruvate is converted to oxaloacetate by pyruvate carboxylase.
- In the cytosol, malate or aspartate is formed from oxaloacetate and is then converted back to oxaloacetate.
- Oxaloacetate is changed into phosphoenolpyruvate by the enzyme phosphoenolpyruvate carboxykinase.
- Phosphoenolpyruvate reverses the processes of glycolysis to produce fructose 1,6-bisphosphate.
