Quiz Glycolysis Pathway

Explanation
Since the proccess of glycolysis is primitive, it does not require complex machinary to work.

Explanation
Glycolysis is anerobic and does not require oxygen. Glucose, a six-carbon sugar is split into smaller molecules and is essential for glycolysis.

Explanation
In the end of the glycolysis proccess, two additional ATP molecules are created along with two pyruvates. The ADP and PGAL are used in the proccess but are not end products.

Explanation
The ATP molecules gets the ball rolling in glycolysis but the release of energy from the breaking apart of glucose catalizes the proccess.

Explanation
The net ATP created in the proccess of glycolysis only represents 2% of the total energy in glucose.

Explanation
In the EMP pathway, also known as glycolysis, a total of 8 ATP molecules are produced. This pathway involves the breakdown of glucose into two molecules of pyruvate. During the process, a net gain of 2 ATP molecules is generated through substrate-level phosphorylation. Additionally, two molecules of NADH are produced, which can be used to generate an additional 6 ATP molecules through oxidative phosphorylation. Therefore, the overall ATP yield from the EMP pathway is 8 ATP molecules.

Explanation
The EMP pathway is also known as glycolysis. Glycolysis is the metabolic pathway that converts glucose into pyruvate, generating ATP and NADH in the process. It is the first step in cellular respiration and occurs in the cytoplasm of cells. The other options mentioned, Kreb cycle, Dark reaction, and Stroma Reaction, are not synonymous with the EMP pathway and refer to different metabolic processes.

Explanation
Glycolysis is the common pathway for both aerobic and anaerobic pathways. It is the initial step in cellular respiration where glucose is broken down into pyruvate. This process occurs in the cytoplasm and does not require oxygen. In aerobic respiration, the pyruvate produced in glycolysis is further broken down in the Tricarboxylic Acid Cycle (also known as the Citric Acid Cycle or Kreb cycle) to produce more energy. In anaerobic respiration, the pyruvate is converted into other byproducts without the need for oxygen. Therefore, glycolysis is the correct answer as it is involved in both aerobic and anaerobic pathways.

Explanation
Glycolysis is the process by which glucose is broken down into pyruvate molecules. Therefore, the end product of glycolysis is pyruvate. ATP and kinase are not the end products of glycolysis, but rather ATP is produced as a result of glycolysis and kinase is an enzyme involved in the phosphorylation of molecules. Carboxyl is not directly related to glycolysis.

Explanation
Hexokinase is the correct answer because high concentration of glucose 6-phosphate inhibits its activity. Hexokinase is an enzyme that catalyzes the phosphorylation of glucose to glucose 6-phosphate, and this product acts as a feedback inhibitor of hexokinase. When the concentration of glucose 6-phosphate is high, it signals that there is already enough glucose 6-phosphate in the cell and the production of more is not needed, thus inhibiting the activity of hexokinase.
