Answer:
D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.
Explanation
In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.
Answer:
Answer would be A
Explanation:
If you cannot read it A is
warm, moist air rises
Answer:
Choice C., High blood glucose levels can result from an overproduction of insulin
Explanation:
Blood sugar levels are regulated by two pancreatic hormones—insulin and glucagon. When blood sugar levels increase, insulin is released (beta cells of the pancreas), it binds to its receptors and consequently increase glucose uptake by cells, which effectively lowers blood glucose levels. On the other hand, when blood sugar levels decrease, glucagon is released (alpha cells of the pancreas), it binds to its cell receptors, and causes glucose to be released into circulation, thereby increasing blood glucose levels.
The labeling of the cell represents.
The label A is Nucleus: The nucleus of the cell carries the hereditary material DNA from one generation to another generation. This carries the traits from one generation to another.
The label B is Cytoplasm: This is the fluid part of the cell which has all the organelles floating in it.
The label C is ribosomes: It is the an organelle present in that that is responsible for the protein synthesis.
The label D is Nucleolus: It is known to be the largest structure in the nucleus of the eukaryotic cell. It helps in the signal recognition pathway.
