Lactic acid fermentation occurs as an alternative to that of aerobic respiration, this occurs in cases where oxygen levels or concentrations within the cells are very low and as a result, is not available for the acceptance of electrons as the final electron acceptor. The cells undergo this process, where essentially, rather mr than using oxygen as the final electron acceptor after producing ATP. NAD+ I believe is able to accept electrons and thus we can produce ATP, again. Glycolysis occurs but rather than moving on to the next stage, Pyruvate molecules are ultimately converted to lactic acid which releases ATP, the extra electrons would go to NAD+ which is needed to keep the reactions going.
Answer:
animal cell are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles
In order to move molecules against the concentration gradients, the cell must have the advantage of Creates energy
<u>Explanation:</u>
When a solute is concentrated to a particular area it is called as concentration gradient. The law of thermodynamics well explains that a molecule moves from area of higher concentration to lower concentration.
If a molecule moves against the concentration gradient it is called as Active transport. For this process to happen the cell needs to energy efficient.
Energy is been released and it is stored in the form of bonds between the atoms during active transport. To maintain the proper balance in the molecules and the balancing of ions active transport is essential.
Answer:
Cellular Respiration
Explanation:
Metabolism is the sum of chemical reactions taking place in the living organisms. Cellular respiration is one such metabolic process. Cellular respiration takes place in in the all organisms in which respiratory substrate such as glucose is oxidised completely in presence of oxygen to produce carbon dioxide, water and energy (ATP). Cellular respiration begins in cytoplasm and completes in the mitochondria of the cell. The energy is used to do work.
The oxidation reaction is given below:
C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + Energy
