MCAT Biology Aid » Organic Chemisattempt, Biochemisattempt, and also Metabolism » Biochemistry and Metabolism » Glycolysis
Explanation:

Erythrocytes (red blood cells) have no mitochondria, and hence cannot usage oxidative phosphorylation to develop extra ATP from pyruvate acquired from glycolysis.

You are watching: Which of the following is not true of the citric acid cycle?

Liver cells (hepatocytes), neurons, and muscle cells (myocytes) can derive some ATP from glycolysis, but then feed the resulting pyruvate into the Krebs cycle in the mitochondria for added power production.


Which of the adhering to biological processes will take place under both aerobic and also anaerobic conditions in humans?


Explanation:

The correct answer is glycolysis. Fermentation is a pathmeans that needs anaerobic conditions to activate. The citric acid cycle and also Krebs cycle are 2 terms for the same procedure, and need aerobic conditions to continue. Glycolysis has pathmeans that account for instances both in the existence and also absence of oxygen.


Explanation:

In glycolysis, 4 ATP molecules made from each unit of glucose, however, two ATP molecules are offered throughout this process, so the net outcome of one round of glycolysis is two ATP molecules. These assets are made using substrate-level phosphorylation, a process in which a phosphorylated molecule transfers its phosphate to ADP or GDP (creating ATP or GTP).

The other options are incorrect. Three NADH2 and one FADH2 are made in one round of the Krebs cycle, not glycolysis. Glycolysis is an anaerobic process and takes location in the cytoplasm, not the mitochondria. Finally, pyruvate products do not necessarily need to enter the Krebs cycle—they have the right to be metabolized anaerobically if inenough oxygen is existing.

Example Question #4 : Glycolysis


Which of the adhering to is a product of glycolysis?


Possible Answers:

O2


Acetyl CoA


NADH


GTP


Glucose


Correct answer:

NADH


Explanation:

In glycolysis, one glucose molecule and 2 NAD+ molecules yield two molecules of pyruvate, 2 molecules of ATP, and two molecules of NADH.

Acetyl CoA is developed from pyruvate at the start fo the Krebs cycle. GTP is a product of the Krebs cycle. Oxygen and also glucose are both reactants in metabolic processes that are derived from outside intake (respiration and also digestion).

Example Concern #5 : Glycolysis


Given the procedure of glycolysis, which of the complying with would serve to allosterically inhibit the rate of glycolysis?


Possible Answers:

Increased oxygen


Increased fructose


Decreased ATP


Increased ATP


Increased glucose


Correct answer:

Increased ATP


Explanation:

The product of glycolysis is ATP, and each cycle offers a net of 2 ATP, thus if tright here were already high levels of ATP in the body, glycolysis would certainly not have to take place as frequently because the body"s power requirements are currently being met. High levels of ATP would serve as an allosteric inhibitor.

Decreased ATP and also enhanced glucose would rise the rate of glycolysis. Increased oxygen or fructose may indirectly increase the price of glycolysis, depending upon other cellular factors.

Example Inquiry #1 : Glycolysis


Which of the complying with assets is not created by glycolysis?


Possible Answers:

Lactic acid


ATP


NADH


Pyruvate


Correct answer:

Lactic acid


Explanation:

Glycolysis is the initially action of cellular respiration. It is responsible for the production of two ATP molecules, two pyruvate molecules, and 2 NADH molecules. Lactic acid is a byproduct of anaerobic respiration in skeletal muscle.

Example Inquiry #7 : Glycolysis


What is the place of glycolysis?


Possible Answers:

The intermembrane space


The cytosol


The outer mitochondrial membrane


The mitochondrial matrix


Correct answer:

The cytosol


Explanation:

The initially action of respiration is glycolysis. All of the measures of glycolysis take place in the cytosol of the cell; this permits prykarotes to percreate glycolysis, and eukaryotes.

Once pyruvate is created from glycolysis, it is transported to the mitochondria to complete the citric acid cycle. The electron transport chain, the final step of cellular respiration, is situated on the inner mitochondrial membrane, and also uses the proton gradient in the intermembrane space.

Example Inquiry #8 : Glycolysis


Which of the complying with is not true of glycolysis?


Possible Answers:

It requires an input of ATP to begin


It is anaerobic


It produces NADH


It occurs in the cytoplasm


It produces 4 net ATP


Correct answer:

It produces four net ATP


Explanation:

Glycolysis produces four total ATP molecules, but just produces 2 net ATP. The procedure calls for an initial investment of 2 ATP to initiate the glycolysis pathmethod. By utilizing 2 ATP and also producing 4, tright here is a net production of 2 ATP.

Glycolysis is an anaerobic procedure that occurs in the cytoplasm. In addition to making ATP, glycolysis also geneprices NADH, which goes to play a function in the electron deliver chain.

Example Question #9 : Glycolysis


Which of the complying with is not a product in the net reaction for glycolysis?


Possible Answers:

Pyruvate


Water


NADH


ATP


ADP


Correct answer:

ADP


Explanation:

The glycolysis reactivity follows two step. The initiation needs the input of two ATP, which become converted to ADP. Later in the process, however, 4 ADP are forced to produce four ATP assets. ADP is consumed in a greater quantity than it is developed, eliminating it from the net assets.

Example Concern #1 : Glycolysis


What kind of enzyme is responsible for initiating the process of glycolysis?


Possible Answers:

Hydrolase


Phosphotase


Phosphorylase


Kinase


Correct answer:

Kinase


Explanation:

The initial reactants for glycolysis are glucose, ATP, ADP, and NAD+. The last commodities are pyruvate, ATP, ADP, and NADH. To acquire from glucose to pyruvate, a number of enzymes are necessary. While learning the names of each enzyme is not commonly vital, it is important to have actually a general understanding of the glycolytic process. The first action is phosphorylation of the reactant glucose, which is completed by hexokinase in the majority of cells, and also by glucokinase in the liver and pancreas specifically. The resultant glucose-6-phosphate then continues via the remaining procedures in glycolysis to create pyruvate.
