Which species is responsible for the blue color that appears during the iodine clock reaction?.

Biology
1 answer:
Nonamiya [84]3 years ago
5 0

Answer:

Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine.

Explanation:

The iodine molecule slips inside of the amylose coil. Iodine - KI Reagent: Iodine is not very soluble in water, therefore the iodine reagent is made by dissolving iodine in water in the presence of potassium iodide.

What would happen to the proton gradient and ATP production after a drug has poisoned the enzyme that combines acetyl CoA and ox
I am Lyosha [343]

Answer:

The best answer to the question: What would happen to the proton gradient and ATP production after a drug has poisoned the enzyme that combines acetyl CoA and oxaloacetate to form citrate? Would be, C: Less NADH production would create to a weaker proton gradient and less ATP production.

Explanation:

The reason comes from remembering that ATP is a molecule that is produced when protons are transferred in a chemical reaction called anabolism to the precursor for ATP, ADP. This process of transference of protons requires the correct work of several chemical compounds, including enzymes and coenzymes, which basically assist enzymes in the management of hydrogen atoms during metabolic processses.

NADH, like others, is a coenzyme whose task is to accept hydrogen atoms and assist in the oxidation-reduction reactions that take place in the body, including the production of ATP. If a poison has stopped the correct transfer of protons by preventing the correct work of both enzymes and coenzymes, then the direct result is the lesser production of NADH and therefore there will be a much less efficient process of proton transfer to produce ATP.

Why is it important to know your blood type?
aivan3 [116]

Answer: The importance of knowing your blood type is to prevent the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it can lead to a clumping of blood cells that can be potentially fatal.

A distribution of class scores on a test is approximately normal with a mean of 75 and a
Anna [14]

Answer:

O A. No, 10.6% of the class scored above her test score

Explanation:

Using the standard normal distribution (Z score) to solve this problem. The formula is as follows:

Z = x - μ/σ

Where;

σ = standard deviation

μ = mean score

x = Edna's score

According to the information given in this question:

σ = 8

μ = 75%

x = 85%

Z = 85 - 75/8

Z = 10/8

Z = 1.25

Using the table of normal distribution probabilities, we check for Z score of 1.2 under 5 = 0.8944

This means that Edna's percentage score is 89.44%. Hence, (100 - 89.44) = 10.56% is above Edna's score in the class

Approximately, 10.6% of the class scored above Edna's test score, meaning that she is not among the top 10% of her class.
