I believe the answer is : A - Evolution
Good luck!
Answer:
Pyruvate kinase
Explanation:
Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.
Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.
The term used for the condition, in which the uptake of nutrients from the small intestine is impaired is malabsorption.
The malabsorption is a condition, in which the small intestine walls become unable to uptake the nutrients in the blood. This condition can be caused by many different reasons, which affect the wall of the intestine. These conditions include infections, trauma, celiac disease, and surgery. Some diseases such as Crohn's disease, pancreatitis (chronic), or cystic fibrosis is also responsible for the malabsorption.
A. True ! Energy can be lost, but not created nor destroyed.
