Answer:
4. The kinetics for the enzymatic processes of microorganisms responsible for decomposition are slowed.
Explanation:
Generally most enzymes work best at optimum temperature of 35-40 degree centigrade, This is because enzymes are proteins, and proteins are sensitive to temperature.
Therefore at low temperature of refrigeration below -18 degree, enzymatic processes of microorganisms need for biochemical activities, oxidative activities and growth are slowdown(thus microorganism population is reduced) . Microorganisms are inactive. Therefore the rate of food decomposition is slowed down,which prolonged nutritional value of the food.
Answer:
The Ozone Layer would repair
Explanation:
CFC's are chlorofluorocarbons. They generally eat the ozone layer. It stands to reason that a reduction in CFC's would reduce the depletion of the ozone layer allowing it to slowly repair itself through natural processes.
Answer:
The complete breakdown of glucose in the presence of oxygen occurs in two stages: glycolysis and citric acid cycle. The first of these stages occur in the cytoplasm of the cell, and the second stage occurs in organelles called Mitochondria.
Explanation:
The breakdown of glucose occurs in two stages. The first stage occurs inside the cytoplasm, it is called glycolysis. when a molecule of glucose undergoes glycolysis, the following are produced:
2 ATP (Adenosine triphosphate) molecules;
2 water molecules;
2 pyruvate molecules and;
2 NADH (Nicotinamide Adenine dinucleotide) molecules
The second stage occurs in an organelle called Mitochondria, it is called citric acid cycle or tricarboxylic acid or Kreb's cycle. In this stage, the two pyruvate molecules from the glycolytic cycle are reduced to carbon(iv)oxide. The following are produced:
2 ATP molecules;
6 NADH molecules;
2 FADH2 (flavine adenine dinucleotide) and;
4 molecules of carbon(iv) oxide.
The NADH and FADH2 molecules are used in the electron transport chain generates as much as 28 ATP molecules.
