For an endergonic reaction, the statement ΔG is positive is
the true statement. So the first option in the given question is the correct
option. Any reaction that requires energy to be absorbed is called an
endergonic reaction. For example, photosynthesis is a great example of
endergonic reaction. In photosynthesis sunlight is required to be absorbed to
complete the reaction. The sunlight acts as the energy required. This type of
reaction is never spontaneous, but requires external force to complete the reaction.
Answer:
Storage proteins serve as biological reserves of metal ions and amino acids, used by organisms. They are found in plant seeds, egg whites, and milk. Ferritin is an example of a storage protein that stores iron. Iron is a component of heme, which is contained in the transport protein, hemoglobin and in cytochromes.

Hope this helps.
Answer:
Mutations that activate the kinase portion of the receptor result in a receptor that is constantly phosphorylated. This causes constitutive activation of downstream signaling and the resulting cell growth and proliferation
Explanation:
The epidermal growth factor receptor (EGF receptor) is a type of receptor tyrosine kinase that recognizes and binds different ligands (including the Epidermal growth factor), which triggers its dimerization through the interaction of the extracellular domains. In humans, several mutations in genes encoding receptor tyrosine kinases have been associated with cancers. It is for that reason that mutated receptor tyrosine kinase genes are well-known oncogenes. Moreover, mutations in several receptor tyrosine kinase genes that lead to constitutive activation by phosphorylation have also been identified. In this case, it is expected that a mutation in the EGF receptor leads to constitutive phosphorylation of the mutant protein, constitutively activating downstream signaling.
