Product Quality · Nutrition and Feeding · Health and Care What determines whether an insect population explodes or just moves Eggs may hatch in spring into parthenogenetic females, the beginning of the new line, to see if we can observe any of these phenomena on captive aphids on.
Explanation:
Answer:
1) Both are surrounded by a cell membrane.
2) Both contain cytoplasm.
3) Only eukaryotic cells have a nucleus.
4) Only eukaryotic cells have membrane-bound organelles.
5) Both tend to be microscopic in size.
6) Only eukaryotes are either multicellular or unicellular.
7) Only prokaryotes are only single-celled.
Answer:
It will be on the cytoplasmic side of the endoplasmic reticulum
Explanation:
The inner mitochondria protein called Adenine Nucleotide Translocator or ADP/ATP carrier protein, maintains the transport of ADP into the matrix of the mitochondria from the cytoplasm for ADP to be available for ATPase synthesis of ATP, from ADP and Pi(inorganic phosphate ion) during chemiosmosis of oxidative phosphorylation in the mitochondria.
The same carrier proetin also convey the synthesized ATPs back to the Cytoplasm for cellular utilization.
Therefore the ATP binding site should at the cytoplasmic side of the E.R, because the cytoplasm of the E.R is the site of deposits of synthesized ATP s, thus proximity of the ATP-binding site to it is needed.
Answer:
Insulin is a protein hormone which binds to the membrane receptor where as steroid hormones bind to the intracellular receptors.
Explanation:
Hormones can be divided into two groups based on their binding with receptor. Some hormones are water soluble like protein or peptide hormone (example is insulin) and catecholamines. These water soluble hormones cannot cross the plasma membrane of the target cell and thus bind to the membrane receptor. Binding to the membrane receptor leads to activation of intracellular enzymes which bring the physiological change. Steroid hormones in the other case can cross the plasma membrane and then bind to the intracellular receptors. The hormone receptor complex then either binds or activates specific portion of DNA to bring the physiological change.
Insulin is made by beta cells islets of Langerhans in the pancreas. It controls the levels of glucose. It is a small protein made of two polypeptides, one of 21 amino acids and the other of 30 amino acids. These two are called A chain and B chain and are linked together by disulphide bonds. The pro-hormone contains an extra stretch called C-peptide. During the maturation process the proinsulin looses the c-peptide to become mature insulin protein hormone. An american company called Eli Lilly, for the first time made recombinant human insulin.
