Liberty University BIOL 101 quiz 5 complete solution correct answer key

For most chemical reactions in the non-living world, the energy required to break bonds in the reactant molecules

In biosynthesis of a protein, energy for bonding amino acids together comes from

A producer organism is called a “producer” because it produces

Physicists define energy as

Reactants like hydrogen and oxygen molecules and are converted into a product like water molecules in the course of

Systems that convert energy from one form to another are

In a long metabolic pathway, the multiple changes made to an initial reactant molecule are entirely controlled by

Energy-releasing reactions drive biosynthetic ones forward by contributing to a pool of

If bacteria can get their energy for life from a single kind of chemical reaction, then that reaction

An endergonic reaction always

An allosteric enzyme

A useful way for a cell biologist to define energy is

In nature, as energy freely changes from one form to another

On a cold day, your cells depend on ________ to maintain an operating temperature of 37 degrees Celsius.

Whenever chemical bonds are broken, energy is __________. Whenever chemical bonds form, energy is __________.

Producer organisms convert _______ energy to chemical energy—the energy of C―H and C―O―H bonds.

Three phosphate groups linked to a ribose sugar which, in turn, is linked to a pyrimidine base known as adenine: this phrase describes the structure of

An excess amount of product accumulates at the end of a metabolic pathway. The product then binds to the allosteric site of the first enzyme along the pathway shutting down the pathway. We call this process

The energy storage molecule that connects endergonic and exergonic reactions, driving endergonic reactions forward, is

Existing chemical bonds between atoms are broken and new ones are formed between different atoms. This process

The activation energy of a reaction can be lowered if the reaction is catalyzed by

A single regulatory molecule can shut down multiple metabolic pathways if it is able to

In respiration, chemical energy is transferred from glucose to ATP. The energy transfer however, is not 100% efficient. In the transfer, some of the energy is lost as

Moving ions across a membrane requires energy when

Which of the following substances would most likely enable a flagellum to drive a bacterium forward through the medium in which it is swimming?

Metabolic pathways

Glucose gets used up in muscle cells because

Within the cell, useful chemical energy is held in stable form as

In building a protein, when amino acids are to be bonded together

Positively charged protons move freely from one side of the mitochondrial membrane to

If moving ions across a membrane requires energy it is because

To derive energy from an ATP molecule

If the final product of a metabolic pathway begins to build up in excess, the pathway can often be slowed down by a process called

Liberty University BIOL 101 quiz 5 complete solution correct answer key Question 1 For most chemical reactions in the non-living world, the energy required to break bonds in the reactant molecules Selected Answer: a. and b. above Question 2 In biosynthesis of a protein, energy for bonding amino acids together comes from Selected Answer: the bonding reaction itself which gives off excess energy as it occurs. Question 3 A producer organism is called a “producer” because it produces Selected Answer: usable chemical energy. Question 4 Physicists define energy as Selected Answer: the ability to make specific changes occur. Question 5 Reactants like hydrogen and oxygen molecules and are converted into a product like water molecules in the course of Selected Answer: a chemical reaction. Question 6 Systems that convert energy from one form to another are Selected Answer: not 100% efficient, the amount of useful energy decreases. Question 7 In a long metabolic pathway, the multiple changes made to an initial reactant molecule are entirely controlled by Selected Answer: the active sites of the enzymes along the pathway. Question 8 Energy-releasing reactions drive biosynthetic ones forward by contributing to a pool of Selected Answer: ATP molecules. Question 9 If bacteria can get their energy for life from a single kind of chemical reaction, then that reaction Selected Answer: is exergonic. Question 10 An endergonic reaction always Selected Answer: generates more energy from forming new bonds than from breaking old bonds. Question 11 An allosteric enzyme Selected Answer: possesses a second site that binds a regulatory molecule. Question 12 A useful way for a cell biologist to define energy is Selected Answer: the ability to make specific changes occur. Question 13 In nature, as energy freely changes from one form to another Selected Answer: energy is not created or destroyed; the total amount stays constant. Question 14 On a cold day, your cells...
