Question 1

_____ involves metabolic reactions that build larger molecules from smaller ones.
A)Catabolism
B)Polymorphism
C)Anabolism
D)Edentualism

Accepted Answer

Anabolism involves metabolic reactions that build larger molecules from smaller ones, such as the synthesis of proteins from amino acids or the synthesis of glycogen from glucose. Catabolism, on the other hand, involves the breakdown of larger molecules into smaller ones, such as the breakdown of glucose to produce energy. Polymorphism refers to the occurrence of different forms or variations of a gene or trait within a population, while edentulism refers to the condition of having no teeth. Neither of these terms are related to metabolic reactions.

Question 2

Which of the following compounds can human cells metabolize for energy? (Check all that apply. )

Accepted Answer

__X__
Lipids
__X__
Alcohol
_____
Water
__X__
Proteins

Question 3

Which of the following forms of metabolism releases the lower amount of energy in the cell?
A)Anaerobic metabolism
B)Aerobic metabolism and anaerobic metabolism release about the same amount of energy.
C)Aerobic metabolism

Accepted Answer

Anaerobic metabolism releases less energy compared to aerobic metabolism because it does not fully oxidize glucose, resulting in less ATP production.

Question 4

_________ contains riboflavin and can pick up two hydrogen ions and two electrons.
A)FAD
B)TPP
C)Coenzyme A
D)NAD

Accepted Answer

FAD (flavin adenine dinucleotide) contains riboflavin and can pick up two hydrogen ions and two electrons. The others listed do not contain riboflavin or do not function in this way. TPP (thiamine pyrophosphate) and Coenzyme A are involved in other types of chemical reactions, while NAD (nicotinamide adenine dinucleotide) can pick up one hydrogen ion and two electrons.

Question 5

A large quantity of ATP molecules is produced during ___________.
A)both aerobic and anaerobic metabolism
B)anaerobic metabolism when adequate oxygen is present in the cell
C)aerobic metabolism when adequate oxygen is present in the cell
D)aerobic metabolism when there isn't sufficient oxygen present in the cell

Accepted Answer

Aerobic metabolism, which occurs in the presence of oxygen, produces a large quantity of ATP molecules. Anaerobic metabolism, which occurs in the absence of oxygen, produces a smaller amount of ATP molecules. Oxygen is a crucial component of the electron transport chain, which is the final stage of aerobic metabolism that produces the majority of ATP. Anaerobic metabolism can occur when there isn't enough oxygen present in the cell, but it produces lactic acid and a much smaller amount of ATP.

Question 6

Metabolic reactions that break down larger molecules into smaller ones are classified as __________.
A)anabolic
B)dynamic
C)metaphysic
D)catabolic

Accepted Answer

Catabolic reactions involve the breakdown of larger molecules into smaller ones, releasing energy in the process. Anabolic reactions, on the other hand, build larger molecules from smaller ones, requiring energy input. Dynamic and metaphysic are not commonly used terms in biochemistry.

Question 7

Check any accurate statements from the list below.
____ATP is a high-energy phosphate compound.
_____Enzymes are changed during the chemical reactions they catalyze.

Question 8

ATP synthesis occurs in which of the following organelles?
A)Golgi apparatus
B)Lysosome
C)Endoplasmic reticulum
D)Mitochondrion

Accepted Answer

ATP synthesis primarily occurs in the mitochondria through oxidative phosphorylation.

Question 9

________ is a component of the coenzyme nicotinamide adenine dinucleotide.
A)Thiamin
B)Niacin
C)Riboflavin
D)Vitamin B-6

Accepted Answer

Niacin, also known as vitamin B3, is a component of the coenzyme nicotinamide adenine dinucleotide (NAD). NAD is involved in many metabolic processes, including energy production and DNA repair. Thiamin, riboflavin, and vitamin B-6 are all B vitamins, but they are not components of NAD.

Question 10

If niacin is not available for the coenzyme nicotinamide adenine dinucleotide (NAD),which of the following would occur to the reaction that requires NAD?

Accepted Answer

The answer of If niacin is not available for the...

Question 11

During glucose catabolism,pyruvate is produced during which of the following metabolic pathways?
A)Citric acid cycle
B)Cytochrome C
C)Electron transport chain
D)Glycolysis

Accepted Answer

Pyruvate is produced during glycolysis, which is the breakdown of glucose into two pyruvate molecules.

Question 12

Which of the following chemical pathways of glucose catabolism produces the highest amount of ATP molecules?
A)Electron chain transport
B)Glycolysis
C)Citric acid cycle
D)Fermentation

Accepted Answer

The electron chain transport is the pathway that produces the highest amount of ATP molecules, generating a total of 36-38 ATP molecules per glucose molecule compared to the 2 ATP molecules produced by fermentation and the 2 ATP molecules produced by glycolysis. The citric acid cycle contributes to the electron chain transport by producing electron donors, but it only generates 2 ATP molecules per glucose molecule.

Question 13

Which of the following compounds can be used for energy? (Check all that apply. )

Accepted Answer

The answer of Which of the following compounds can be...

Question 14

Energy is defined as____________.
A)the capacity to perform work
B)movement
C)change
D)transformation

Accepted Answer

Energy is defined as the capacity to perform work. Movement, change, and transformation are all factors that may involve energy, but they are not comprehensive definitions of energy itself.

Question 15

Check any accurate statement from the list below.
_____Glycogenolysis is the reverse of glycolysis.
____Glycogen is stored in the liver and muscles.
_____Glycogenolysis occurs both in the liver and muscles and releases glucose into the bloodstream.
_____Glycogen catabolism proceeds at a higher rate when excess glucose is available.

Question 16

Series of specific chemical reactions in the cell are known as__________.
A)chemical pathways
B)chemical transformations
C)transformative changes
D)energy expenditures

Accepted Answer

Chemical pathways is the common term used to describe the series of specific chemical reactions that occur within a cell.

Question 17

Which of the following compounds enters the citric acid cycle?
A)Pyruvate
B)Cytochrome C
C)Acetyl CoA
D)Glucose

Accepted Answer

Only acetyl CoA enters the citric acid cycle as it is the product of the oxidation of pyruvate or fatty acids. Cytochrome C is a protein involved in the electron transport chain and glucose must be broken down into pyruvate through glycolysis before it can enter the citric acid cycle.

Question 18

___________ is the breakdown of glycogen into glucose molecules.
A)Glycolysis
B)Glucogenesis
C)Glycogenolysis
D)Ketogenesis

Accepted Answer

Glycogenolysis is the breakdown of glycogen into glucose molecules, which can then be used by the body for energy. Glycolysis refers to the breakdown of glucose itself, while glucogenesis is the process of synthesizing glucose from non-carbohydrate sources. Ketogenesis refers to the production of ketone bodies from fatty acids.

Question 19

The organic cofactors that help enzymes catalyze reactions are called __________.
A)cosubstrates
B)coenzymes
C)products
D)reactants

Accepted Answer

Organic cofactors are called coenzymes. Cosubstrates are small molecules that bind temporarily or permanently to the active site of an enzyme, but they are not organic cofactors. Products and reactants are not organic cofactors.
