The weighted average cost of capital (WACC) is the rate that a company is expected to pay on average to all its security holders to finance its assets. The WACC is commonly referred to as the firmâs cost of capital.Importantly, it is dictated by the external market and not by management.The WACC represents the minimum return that a company must earn on an existing asset base to satisfy its creditors, owners, and other providers of capital, or they will invest elsewhere.mportantly, it is dictated by the external market and not by management.

Most eukaryotic cells have mitochondria, which produce ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial inner membrane, electrons from NADH and succinate pass through the electron transport chain to oxygen, which is reduced to water.n the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions. These reactions are coupled to the creation of a proton gradient across the mitochondrial inner membrane. There are three proton pumps: I, III, and IV.
Mitochondria and Energy. Mitochondria, an organelle found in both plant and animal cells, contains protein-rich components called cristae, which produce ATP. ATP is converted to adenosine diphosphate (ADP), a process which releases energy.denosine triphosphate (ATP) is a high-energy molecule contained in the nucleus of eukaryotic cells. This molecule provides all energy needed for various physiological processes, and is renewed through oxidation, so a cell always contains a supply of ATP to fuel the energy demands of the organism.
