Answer:
In anatomical directional terminology, the esophagus is <u>posterior</u> to the mouth (option d).
Explanation:
The esophagus is a tubular organ that is part of the digestive system and its function is to carry food from the mouth to the stomach. The anatomical relationship of the proximal end of the esophagus, with respect to the mouth, is posterior and inferior, its distal end also being located above the stomach.
This anatomical relationship allows the direction of food movement to be mouth → esophagus → stomach.
Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
They are found in bacteria and eukaryotes is false
Answer:
A) exergonic; protons; glycolysis
Explanation:
The synthesis of ATP from ADP and Pi is an exergonic reaction. In mitochondria, ATP synthesis is driven by the flow of proton down a concentration gradient established by glycolysis.
