The chemiosmotic model requires an intact outer mitochondrial membrane. is supported by the observation that, when isolated mito

Rudik [331]

Answer:

requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.

Explanation:

The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.

Properties of minerals :

1. They have characteristic chemical composition

2. They have highly ordered atomic structures

3. They have several physical properties such as hardness, luster and cleavage.

Thus, Iron, Gold, Aluminum, Sapphires and Copper are the metallic minerals while Quartz, Calcite, Diamond, Rubies, Emerald, Topaz, Coal and Petroleum are the non-metallic minerals.
