g Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phos
masha68 [24]

Answer:

- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.  

- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.  

- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.

Explanation:

Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.

Enzymes that catalyze consecutive steps in a metabolic pathway often cluster together in a cell.
Mama L [17]

Answer: pathway intermediates are prevented from entering alternative metabolic pathways

Explanation: the clustering of enzymes in a metabolic pathway ensures that the product of one enzyme is efficiently transferred to the next enzyme in the pathway. So, the clustering prevents pathway intermediates from being diverted into alternative metabolic pathways.
