Answer:
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+
Explanation:
Pyruvate is converted to lactate by the enzyme lactate dehydrogenase under anaerobic condition.
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+ . This is because every glucose molecule that will be converted into pyruvate, two NADH molecules are produced and there is need for the NADH molecules to be oxidised back to NAD+ to ensure the continuity and maintenance of glycolysis.
Answer: D
Explanation:osmosis is the movement of molecules from a region of lower concentration to a region of higher concentration through a semi permeable membrane.
By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.
The answer would be A. Mica.
Answer:Plant cells are somewhat unique because unlike animal cells, plant cells contain both a cell wall and cell membrane. ... The cell wall is a protective layer outside the cell membrane that also provides support for the cell's structure.
