9. Based on the information in the table, which enzyme is not functioning in this strain of mold?
Sedbober [7]

Based on the information in the table,

  • the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
  • the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.

<h3>What are enzymes?</h3>

Enzymes are organic catalysts that speed up the chemical reactions occurring in the body.

Enzymes are very essential in most metabolic reactions occurring in the body.

The deficiency or inactivity of an enzyme in the body will lead to an accumulation of the substrate on which the enzyme acts on.

Based on the information in the table,

  • the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
  • the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.

in conclusion, enzymes are important for biochemical reactions.

Answer: See below

Explanation:

Solar energy: Advantages: Solar energy is pollution free and causes no greenhouse gases to be emitted after installation. Disadvantages: Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.

Wind energy: Advantages: It doesn't pollute air like power plant relying on combustion of fossil fuel. Disadvantages: Wind turbines can be a threat to wildlife (e.g. birds, bats).

Hydroelectric energy: Advantages: Hydroelectric energy is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Disadvantages: Electricity generation and energy prices are directly related to how much water is available. A drought could potentially affect this.
