Is someones thought considered homeostasis?

One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as

solniwko [45]

1. Regulation of glucose blood levels is an example of negative feedback mechanism.

Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.

Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.

• Pancreatic cells-sensors

• Insulin-control system

• Body cells- effector cells

2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.

This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.

3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.

Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.

Depurination of purine bases results in an apurinic site. Assume a single depurination event occurs in the GC base pair of the s

Naily [24]

F) ...TAAT...
...ATTA...
Single depurination event occurred in the GC base pair of the sequences so find the C in the 1st sequence & find the G in the 2nd sequence. These are not repaired, so the C & G are eliminated. Then 2 rounds of replication occur in the same spots where the C & G were. Take the letter previous to the empty spots & replicate it in the empty spots. TAAT. ATTA

If the anticodon of an alanyl-tRNA is IGC (inosine-guanine-cytosine), to which of the following codons would it bind? The codon

vichka [17]

Explanation:

Possible anticodon sequences include: GCA, GCC, or GCU.

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other biological macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.

DNA encodes an organism's genetic information; this undergoes transcription, where RNA is formed. Codons are three nucleotide bases encoding coding and amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine specific amino acid, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made in translation; the four RNA nucleotides (Adenine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG Begins protein synthesis.In wobble pairing, the same tRNA can recognise different codons of its amino acid. Thus for the third positions on codons, alanyl-tRNA (inosine-guanine-cytosine) can recognise GCA, GCC, or GCU.
