Answer:
Since a proton gradient is essential across the inner mitochondrial membrane during oxidative phosphorylation for ATP generation, the introduction of gramicidin will lead to a reduction in ATP synthesis because it increases the permeability of the inner mitochondrial membrane, allowing protons to flow freely, subsequently eliminating the electrochemical gradient required for ATP production. While electron transport remains unaffected as it relies on NADH and FADH2 availability, proton pumping continues; however, it becomes ineffective since protons can move in either direction.
Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
The correct option is: A. Species A possessed larger jaw muscles than species B.
Significant jaw muscles are linked to a more primitive diet. It is thought that the reduction of jaw muscles is part of the evolutionary process. This is a way to create room for a larger brain.
The benefit of reduced gametophytes in seed plants is that they obtain nutrients from the sporophytes. Gametophytes are tiny and can develop from spores that are kept within the parental sporophyte's sporangia. This setup shields the growing gametophyte from environmental stress, allowing it to absorb nutrients from the sporophyte.
A sequence of amino acids folded and twisted into a molecule.
