The correct answer for the question that is being presented above is this one: "<span> d. All of the above." Th</span>e following statements about the dark reactions is true are the following: Dark reactions occur in the thylakoids of chloroplasts; Light energy is <span>converted to chemical energy during the dark reactions; Carbon dioxide is converted to sugar using ATP and NADPH during the dark reactions.</span>
Here are the answers:
1. WHAT YOU WILL BE LOOKING FOR AS EVIDENCE OF REACTION IN THIS EXPERIMET IS FORMATION OF OXYGEN BUBBLES.
This is because, the catalase enzyme on which this activity is based is an enzyme that speeds up the rate of decomposition of hydrogen peroxide in the cells, breaking it down to oxygen and water. Thus, when this reaction is taking place you will notice that bubbles will form in the test tube. These bubbles is the oxygen gas that is been given off. The presence of the bubbles indicate that the reaction is occurring.
2. YES, THE CATALASE ENZYME WAS PRESENT IN THE PLANT TISSUE THAT WAS TESTED.
The catalase enzyme is present in all plants. The plants need the enzyme to help them breakdown hydrogen peroxide into water and oxygen. This is because the hydrogen peroxide is very toxic to the plant cells and can destroy them, thus the hydrogen peroxide has to be broken down into water and oxygen immediately it is formed.
3. YES, THE CATALASE ENZYME WAS PRESENT IN THE ANIMAL TISSUE TESTED.
In animals, the catalase enzyme is found in great number in the liver. As a result of the metabolic reactions which occur in the liver, hydrogen peroxide is always produce in the liver. The hydrogen peroxide is very toxic to the liver cells and has to be getting rid of on an immediate basis. The catalase is the enzyme which breakdown the hydrogen peroxide into water and oxygen which are not toxic to the cells.
Simple explanation: they both attach to amino acids.
Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water. This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive. The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.
