Question 1

What process make bread dough rise?&#10;A)glycolysis&#10;B)oxidative phosphorylation&#10;C)fermentation

Accepted Answer

The process that makes bread dough rise is fermentation, specifically yeast fermentation. Yeast ferments the sugars in the dough, releasing carbon dioxide gas, which gets trapped in the gluten matrix of the dough and causes it to rise. Glycolysis and oxidative phosphorylation are involved in cellular respiration, not bread making.

Question 2

What process makes sure enzymes are at the optimal pH to function the best inside a cell?&#10;A)response to stimuli&#10;B)cytokenesis&#10;C)homeostasis

Accepted Answer

Homeostasis is the process by which a cell maintains stable internal conditions, such as pH, temperature, and nutrient levels. This ensures that enzymes are able to function optimally inside the cell by providing them with the conditions they need to perform their functions. If the pH level were to fluctuate outside of the optimal range for a particular enzyme, it could denature and become non-functional. Homeostasis helps to prevent these kinds of disruptions and ensures that enzymes can function effectively.

Question 3

Where in the eukaryotic cell does the Citric Acid cycle occur?&#10;A)Golgi body&#10;B)mitochondrion&#10;C)chloroplast

Accepted Answer

The Citric Acid cycle, also known as the Krebs cycle, occurs in the mitochondrial matrix of eukaryotic cells. The Golgi body is responsible for processing and packaging proteins, while the chloroplast is found only in plant cells and is responsible for photosynthesis.
