how does atp provide the energy cells need

Answers

Answer:

Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

ATP provides the energy required by cells by releasing a phosphate group.

ADENOSINE TRIPHOSPHATE (ATP):

Adenosine triphosphate (ATP) is a biological molecule that stores and releases energy for living cells.

Structurally, ATP is made up of three components namely: phosphate group, adenine base and ribose sugar.

ATP stores energy when a phosphate group is added to an ADP molecule while it releases energy when a phosphate group is released from the ATP molecule to form ADP and inorganic phosphorus (Pi).

Therefore, ATP provides the energy required by cells by releasing a phosphate group.

What is a substrate?
a molecule that acts as a catalyst
a place on the enzyme where the reaction occurs
a place on the product where the enzyme fits
a reactant that is catalyzed by an enzyme

Answers

Answer:

D. a reactant that is catalyzed by an enzyme

Explanation:

A substrate is a reactant that is catalyzed by an enzyme. Therefore, the correct statement is option D.

What is a catalyst?

A substrate is a reactant molecule that binds to the active site of an enzyme and the enzyme then chemically transforms the substrate through a series of catalytic reactions.

Enzymes are the catalysts that are used to increase the rate of biochemical reactions by lowering down the activation energy that is required for the reaction to occur. The substrate when binds to the active site of the enzyme, it forms an enzyme-substrate complex followed by its conversion into one or more products. When the product is formed, enzyme gets released from the product.

A catalyst is a substance which is used to lower down the activation energy required by the reaction, thereby, increasing the reaction rate to form a product.

Therefore, substrate is a reactant that is catalyzed by an enzyme.

What is bacteria?

Bacteria are unicellular organisms that are very tiny. Bacteria can be found practically anywhere on Earth and play an essential role in the ecosystems that exist there. Some animals are able to survive in environments with both high temperatures and high pressures.

Both plant and animal cells store their genetic material in the form of chromosomes, which are linear structures. Bacteria do not possess a truly organized nucleus and instead contain a single chromosone that is round. Plasmids are tiny circular pieces of genetic material that can be carried by some bacteria. These plasmids carry additional genetic material.

Describe the term "semi-permeable" (or "selectively-permeable) membrane. Why is it important?

Answers

Answer:

A semi-permeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute. Depending on the membrane and the solute, permeability may depend on solute size, solubility, properties, or chemistry. How the membrane is constructed to be selective in its permeability will determine the rate and the permeability. Many natural and synthetic materials which are rather thick are also semipermeable. One example of this is the thin film on the inside of the egg.

Explanation:

An example of a biological semi-permeable membrane is the lipid bilayer, on which is based on the plasma membrane that surrounds all biological cells. A group of phospholipids (consisting of a phosphate head and two fatty acid tails) arranged into a double layer, the phospholipid bilayer is a semipermeable membrane that is very specific in its permeability. The hydrophilic phosphate heads are in the outside layer and exposed to the water content outside and within the cell. The hydrophobic tails are the layer hidden in the inside of the membrane. The phospholipid bilayer is most permeable to small, uncharged solutes. Protein channels are embedded in or through phospholipids, and, collectively, this model is known as the fluid mosaic model. Aquaporins are protein channel pores permeable to water. Information can also pass through the plasma membrane when signaling molecules bind to receptors in the cell membrane. The signaling molecules bind to the receptors, which alters the structure of these proteins. A change in the protein structure initiates a signaling cascade. The G protein-coupled receptor signaling provides is an important subset of such signaling processes.

Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above

Answers

Answer:

D

Explanation:

All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.

What are nonnative species?

Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.

Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

They are employed in restocking efforts, to replace native species, and for commercial purposes.

Thus, the correct option is D.

Explanation:

The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones

Adrenal glands are a type of endocrine glands that release hormones that include adrenaline into the blood. Thus, the correct option is B

Endocrine glands secrete their products directly in the surrounding interstitial fluid or blood, and not through ducts.

Adrenal glands are a pair of endocrine glands that are present superior to each kidney. It comprises of two distinct regions - adrenal cortex and adrenal medulla.

Adrenal cortex is the outer region of the adrenal gland that produces and secretes hormones like mineralocorticoids, glucocorticoids and androgens.

Adrenal medulla is the inner region of the adrenal gland and produces and secretes the hormones adrenaline and noradrenaline.
