Answer:

True.

Explanation:

Yes, analyses of enzymes found in the blood are used as indicators of tissue damage in the heart, liver, muscle etc has occurred. This leakage of enzymes into the bloodstream tells us whether the tissue is damaged or not. Lactate dehydrogenase is a type of enzyme which is used as indicator which is responsible for the interconverts lactate and pyruvate. The concentration of this enzyme in the blood tells us about tissue damage.

Answer:

a. True

Explanation:

The co enzyme used for this reaction is NADH+, here H+ acts as co substrate.

This is required to find the tissue damage that has occurred in our body which resulted in leakage of cellular enzymes into the bloodstream.

This coenzyme is used for conversion of lactose dehydrogenase.

What is the basic definition of carbohydrates
ikadub [295]

Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.

Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.  

Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain  three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.

Sugar dissolves in water - Physical change

Eggs turn into an omelet. _____Chemical change

Milk sours. Chemical change

A popsicle melts. _____Physical change

Turning brownie mix into brownies. Chemical change

Explanation:

Matter undergoes two types of changes: physical changes and chemical changes.

A physical change is one that affects only the physical properties of a substance such as colour, size, shape, etc., and in which no new substances are formed. Physical changes are easily reversible.

Chemical changes are changes which affect the chemical characteristics and properties of a substance such as reactivity, acidity, basicity, etc., resulting in the formation of new substances.

The following changes below are categorized as either physical or chemical changes based on which of the properties of the substance is affected and whether new substances result or not.

If 4520 kj of heat is needed to boil a sample of water, what is the mass of water
Cerrena [4.2K]

Answer:

1,085g of water

Explanation:

If we have the value 4520kj is because the question is related to Energy and heat capacity. In this case, the law and equation that we use is the following:

                                                  Q= m*C*Δt  where;

Q in the heat, in this case: 4520kj

m is the mas

Δt= is the difference between final-initial temperature (change of temperature), in this exercise we don´t have temperatura change.

In order to determine the mass, I will have the same equation but finding m

                                          m= Q/C*Δt    without   m=Q/C

So: m= 4,520J/4.18J/g°C

      m= 1,0813 g

Which will contain the greater number of moles of potassium ion: 30.0 ml of 0.15 m k2cro4 or 25.0 ml of 0.080 m k3po4?
Dahasolnce [82]
<span>30.0 ml of 0.15 m K2CrO4 solution will have more potassium ions. Let's see the relative number of potassium ions for each solution. Since all the measurements are the same, the real difference is the K2CrO4 will only have 2 potassium ions per molecule while the K3PO4 solution will have 3 potassium ions per molecule. K2CrO4 solution 30.0 * 0.15 * 2 = 9 K3PO4 solution 25.0 * 0.080 * 3 = 6 Since 9 is greater than 6, the K2CrO4 solution will have more potassium ions.</span>
