I will say Large piscivorous fish since i figure that it eats it.
Answer:
Explanation:
Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.
pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD
The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.
If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme. <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.
Answer:
Rise of population and over-consumption resources are key factors of climate change.
Explanation:
- The fact that climate change is real and is happening at a very fast rate. The impacts of which can be seen in terms of the increase in sea levels.
- The rise in global average mean temperatures, an increase in the melting of Greenland and Antarctic glaciers. The exposure of barren land beneath the antarctic continent.
- Therefore the scientific community s very concerned about the massive depletion of resources and the exposure of the earth's surface to solar radiation.
All cells have a protective covering known as cell membrane. In plants, the cell membrane is further protected by another layer called cell wall. All the organelles present inside the cells are membrane bounded structure.
Cell membranes are made up of phospholipid bilayer with extrinsic and intrinsic proteins. From the studies on the plasma membrane structure, it was found that the protein fingerprint of MITOCHONDRIA and CHLOROPLAST are most similar to the cell membrane.
