.'ll AT&T; 2:09 PM @ 50%. EXTRA CREDIT.docx 9The neurotransmitter c acid (GABA) is synthesized from the amino acid glutamate. The structures of both molecules are shown below GABA Which type of enzyme catalyzes the conversion of glutamate to GABA? A) kinase b) transferase c) decarboxylase d) dehydrogenase 10. Enzymes catalyze chemical reactions by stabilizing: a) the substrate b) the product c) the transition state d) the equilibrium 1. The Gibbs free energy equation can be used to predict whether a reaction will proceed spontaneously. For which relative values of H and will a spontaneous reaction always occur? A) a positive AH and a negative AS b) a positive AH and a positive AS c) a negative H and a positive AS 12. Which type of molecule is least likely to be found in a eukaryotic cell membrane? A) phospholipid b) 13. Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause the blood pH to: a) increase, because the neural mechanisms that remove acid from the blood will be activated b) increase, because the partial pressure of CO, in the blood will decrease c) decrease, because the affinity of hemoglobin for oxygen will be increased d) decrease, because the work associated with increased ventilation will consume more O. 14. Scientists have hypothesized that mitochondria evolved from acrobic heterotrophic bacteria that entered and established symbiotic relations with primitive aerobic to thic hunothasis tha h Open With PrintExplanation / Answer
Answer (9): (c) Decarboxylase: Glutamic acid decarboxylase (GAD) is an enzyme that catalyzes the decarboxylation of glutamate to GABA and CO2. From the structure we can see that we have to remove one carboxylic group from glutamate to get GABA and as a name suggest Decarboylase can do the same.
Answer (10): c)Transition state: the main function which any catalyst do is that it lowers the activation energy and activation energy can be brought down by lowering the trainsition state means after stabilizing the transition state.
