Pyruvate undergoes fermentation if no oxygen is present. This is called anaerobic reaction. Can undergo lactic acid or alcoholic fermentation.
Answer:
An important example of negative feedback is the control of blood sugar. After a meal, the small intestine absorbs glucose from digested food. Blood glucose levels rise. Increased blood glucose levels stimulate beta cells in the pancreas to produce insulin.
Answer:
c. requires the action of initiation factors.
Explanation:
Transcription is the process by which a fragment of DNA (e.g., a gene) is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA) molecule which is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation. Initiation factors are proteins capable of binding the ribosome in order to promote (or prevent) the initiation of translation. In prokaryotic cells, the initiation factors IF1, IF2 and IF3 (IFs) are required for the selection and the quantity of the protein produced. In eukaryotic cells, translation initiation occurs when an initiator tRNA, 40S, and 60S ribosomal subunits are assembled by eukaryotic initiation factors (eIFs) into an 80S ribosome on the initiation codon of an mRNA. In eukaryotes, translation initiation is promoted and regulated by at least twelve eIFs (e.g., eIF1, eIF1A, eIF2, eIF3, eIF4, eIF5, eIF5A, eIF5B, etc) which are composed of many polypeptides.
Answer:
In my opinion I like North Padre Island better. A lot lot less commercialized and less expensive too. But, there are a lot more choices for different hotels on the beach in South Padre Island. North Padre also lets you drive on the beach and pick the spot you would like to be at or just enjoy seeing the beach
Explanation:
The anaerobic one would outcompete the other.
This is because anaerobic respiration occurs in the abscence of oxygen whereas aerobic respiration relies on the oxygen for survival.
If the environment has oxygen both anaerobic and aerobic respiration take place. But if, the environment lacks oxygen, anaerobic respiration takes place whereas aerobic respiration does not.
Hope it helped!
