The endergonic chemical reactions are the one that need input of energy. Their products have higher energy content than the substrates. ATP is the energy currency of cells and serves as energy source for endergonic reactions. Hence, consumption of ATP during the endergonic chemical reaction reduces ATP concentration in the system.
The scenario that best describes a mutually beneficial relationship with fungi in an ecosystem is fungus growing on the leaves of plants. The correct answer is B.
The part of the phospholipid bilayer that interacts with water would be the hydrophilic portion consisting of the polar phosphate group. The hydrophobic tails which are the fatty acid chains will not interact with the water present in the aqueous environment.
