A glycolysisis a set of metabolic reactions that occur in the cytosol of cells and are part of the process of cellular respiration.
These reactions are catalyzed by several enzymes and, at the end of the process, the formation of ATP for the cells occurs.

A respiratory chain it is an extremely important process for the survival of living beings, therefore, it is a subject that is very demanded in the ENEM tests and in the main entrance exams in the country.
Our team has prepared a list of exercises on glycolysis so you can test your knowledge about this step of cellular respiration.
Take the opportunity to save the list in PDF and consult the template at the end of this post!
1) Glycolysis is an important process that takes place inside the cell in which a glucose molecule is broken down:
a) in a molecule of pyruvic acid.
b) into two molecules of pyruvic acid.
2) (UEM) Mark the correct alternative regarding cellular respiration.
a) Glycolysis is the conversion of glucose to pyruvic acid.
b) The Krebs cycle consists of converting pyruvic acid into lactic acid.
c) In the respiratory chain, hydrogen is transported to form pyruvic acid.
d) In the Krebs cycle, hydrogen and molecular oxygen are transported and water is produced.
e) The entire process of cellular respiration takes place within the mitochondria.
3) (UEA) Aerobic respiration can be divided into three phases, called glycolysis, the Krebs cycle and the respiratory chain. As for the locations of the cell where these phases occur, it can be stated that:
a) Glycolysis, the Krebs cycle, and the respiratory chain occur within the mitochondria.
b) Only glycolysis and the Krebs cycle occur inside the mitochondria.
c) Only the Krebs cycle and the respiratory chain occur inside the mitochondria.
d) Only glycolysis and the respiratory chain occur inside the mitochondria.
e) Only the respiratory chain occurs inside the mitochondria.
4) Analyzing the alternatives below, mark the one in which the place where the glycolysis process takes place is indicated.
a) In the mitochondria.
b) In the chloroplast.
c) On the ribosome.
d) in the endoplasmic reticulum.
e) In the cytosol.
5) Cellular respiration is a process that guarantees the production of energy necessary for the survival of living beings. Analyze the alternatives below and mark the one that does not indicate one of the stages of cellular respiration.
a) Glycolysis.
b) Oxidative phosphorylation.
c) Krebs cycle.
d) Calvin cycle.
6) (UFPA) The process of cellular respiration is responsible for:
a) consumption of carbon dioxide and release of oxygen to the cells.
b) synthesis of energy-rich organic molecules.
c) reduction of carbon dioxide molecules into glucose.
d) incorporation of glucose molecules and oxidation of carbon dioxide.
e) release of energy for vital cellular functions.
7) Glycolysis can be divided into two stages, an investment phase and a compensation phase. In the investment phase, __ ATP is used, and in the compensation phase, ___ ATP is produced. Analyze the alternatives and mark the one that completes, respectively and appropriately, the two spaces above.
a) 1 and 2.
b) 2 and 2.
c) 2 and 3.
d) 2 and 4.
e) 3 and 5.
8) Glycolysis is one of the stages of cellular respiration, the process responsible for producing the ATP needed by the body. Regarding glycolysis, mark the alternative incorrect:
a) Glycolysis encompasses about ten different chemical reactions.
b) In glycolysis, glucose is broken down into two molecules of pyruvic acid.
c) Glycolysis takes place in the mitochondrial matrix.
d) The positive ATP balance at the end of glycolysis is two molecules.
e) Glycolysis is an anaerobic process.
9) (UFRGS) Animal cells need oxygen, enzymes and substrate to produce energy. Regarding the energy production process, consider the statements below.
I — Oxidative phosphorylation occurs in mitochondria.
II — In the aerobic phase, there is a high production of ATP.
III — Glycolysis has an aerobic and an anaerobic phase.
Which ones are correct?
a) I only.
b) II only.
c) Only I and II.
d) Only II and III.
e) I, II and III.
