Concept explainers
(a)
Interpretation: To characterize the change of citrate to isocitrate in terms of carbon atom as (1) a C6 to C6 change, (2) a C6 to C5 change, (3) a C5 to C4 change, or (4) a C4 to C4 change.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and
The citric acid cycle is included in the common
(b)
Interpretation: To characterize the change of succinate to fumarate in terms of carbon atom as (1) a C6 to C6 change, (2) a C6 to C5 change, (3) a C5 to C4 change, or (4) a C4 to C4 change.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and
An overview of the citric acid cycle is as follows:
The citric acid cycle is included in the common metabolic pathway because the reactions in this stage are the same for different kinds of food.
(c)
Interpretation: To characterize the change of malate to oxaloacetate in terms of carbon atom as (1) a C6 to C6 change, (2) a C6 to C5 change, (3) a C5 to C4 change, or (4) a C4 to C4 change.

- You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?arrow_forwardDescribe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo. If modifying the protein, what is one thing you have to consider in regards to maintaining the protein’s function?arrow_forwardThe following table is from Kumar et. al.

- The following figure is from Caterina et al. The capsaicin receptor: a heat activated ion channel in the pain pathway. Nature, 1997. Black boxes indicate capsaicin, white circles indicate resinferatoxin. You are a chef in a fancy new science-themed restaurant. You have a recipe that calls for 1 teaspoon of resinferatoxin, but you feel uncomfortable serving foods with "toxins" in them. How much capsaicin could you substitute instead?arrow_forwardWhat protein is necessary for packaging acetylcholine into synaptic vesicles?arrow_forward1.
