The answer is B. Periosteum
Answer:
The answer is- A bundling relationship
Explanation:
Bundling is defined as when a company packages some of their products or services together as a single combined unit, often for a lower price than they would charge the customers if the items are sold independently or separately. This helps to facilitate the convenient sale of products or services from one company.
An example could be if Oral-B decides to sell both their toothpaste and toothbrush together as a single combined unit at a lower price than if selling the toothpaste or toothbrush separately.
BioMark Lifesystems' arrangement with the producer of syringes and test tubes to have diagnostic substances sold to laboratories in a package along with the syringes and tubes is called bundling relationship.
Answer:
The reaction is at equilibrium
Explanation:
The Krebs cycle is an aerobic pathway because the final electron acceptor required is oxygen.
The most common situation leading to a disruption in the function of Krebs cycle is the lack of oxygen to accept electrons in the electron transport chain.
The conversion of citrate to isocitrate (isomerization), is catalyzed by the enzyme, aconitase (also known as aconitate hydratase). The hydroxyl (alcohol) group of citrate is moved to an adjacent carbon so that it can be oxidized to form a keto group.
This reaction involves generation of an enzyme-bound intermediate, cisaconitate. At equilibrium, there exists 90% citrate, 3% cisaconitate, and 7% isocitrate; hence the equilibrium of aconitase lies toward citrate formation.
Although the aconitase reaction does not require cofactors, it requires ferrous (Fe2+) iron in its catalytic mechanism. This Fe2+ is involved in an iron–sulfur center, which is an essential component in the hydratase activity of aconitase.
According to Gibb's free energy:
ΔG = 0 - Reaction at equilibrium.
ΔG > 0 - non-spontaneous reaction.
ΔG < 0 - spontaneous reaction.
