1. Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) . 2. A(n) is a molecule that can bind to an enzyme and prevent the enzyme from working. There are two types: a(n) binds to the active site of the enzyme; a(n) binds elsewhere on the enzyme. 3. Enzymes speed up chemical reactions by lowering the , which allows the reaction to proceed much more quickly. 4. During an enzymatic reaction, a molecule of binds to the enzyme and is broken down into one or more molecules of , which are released. 5. The specific location within an enzyme molecule where the substrate binds is called the .

Answers

Answer:

1.) Lactase is an example of ENZYME.

2.)An INHIBITOR is a molecule that can bind to an enzyme and prevent the enzyme from working.

3.)Enzymes speed up chemical reactions by lowering the ACTIVATION ENERGY,

4.) a molecule of SUBSTRATE binds to the enzyme and is broken down into one or more molecules of PRODUCT which are released.

5.) The specific location within an enzyme molecule where the substrate binds is called the ACTIVE SITE.

Explanation:

An enzyme is defined as the substances that aids in the breaking down of complex food substances, taken in by animals, into simple, soluble and diffusible substances before they can be absorbed into the body. In the enzymatic reactions, a molecule of SUBSTRATE binds to the ACTIVE SITE of an enzyme and is broken down into one or more molecules of PRODUCT which are released.

There are different types of enzymes which are named according to the type of good they digest, these include:

--> Lactase: breaks down Lactose

--> proteases: breaks down proteins

--> Amylases: breaks down carbohydrate

Enzymes have the following characteristics:

--> They are proteins

--> They are specific in action. For example Lactase can only act on lactose.

--> They can be inactivated by INHIBITORS.

--> They are sensitive to temperature

--> They speed up a reaction by lowering the ACTIVATION ENERGY

Heat and light on Earth are unevenly distributed because they cannot receive heat and light equally in all parts of the earth.

Answers

Answer:

True

Explanation:

The earth receives unequal amount of light energy and heat energy form the sun. There is variation in the solar energy at different parts of the world due to factors like atmospheric circulation as well as the distribution of the land and the sea.

The main factors which results in the unevenly distribution of the heat and light from the sun to the earth are :

length of the daythe angle of inclination of the rays of the sunearth's rotationconfiguration of the land patternstransparency of the atmosphere

The sun provides more light and heat at the equatorial regions than the polar regions.

how meiosis turn one cell into four new sex cells?

Answers

Answer:

A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.

Explanation:

During sexual reproduction, meiosis produces the sex cells that combine to make new children.

Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.

Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.

The ___ of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The ___ of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, ____ either break or form.
Thus, water absorbs or releases a great deal of ____, helping to moderate temperatures.
Water is a versatile ____.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved ______.

Answers

Answer:

The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.

The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.

When water warms or cools, hydrogen bonds either break or form.

Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.

Water is a versatile solvent.

Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.

Explanation:

The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.

Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.

Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.

The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.

Name & describe the six essential activities of the digestive tract.

Answers

Answer:

Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.

Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.

Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.

Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.
