How do protons contribute towards making ATP?...

Biology
1 answer:
ivanzaharov [21]4 years ago
6 0

Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.

Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.

To understand the chemical basis of inheritance, we must understand the molecular structure of DNA.
earnstyle [38]

Answer:

C) reductionism

Explanation:

The approach of reductionism is applied to decipher the basic concepts that rule some complex life processes. In this approach, the complex life processes can be interpreted by explaining the physical and chemical structure of involved components and their interactions. DNA molecules store genetic information. Inheritance means the transfer of genetic traits from one generation to the next. Therefore, the chemical structure of DNA is the application of reductionism to understand the chemical basis of inheritance.

Desmosomes form channels that allow each cardiocyte to electrically stimulate its neighbors. True False
dimulka [17.4K]

Answer:

False

Explanation:

The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.
