Question:

What role does glucose play in the TCA (Krebs) cycle?

Savanna G.
Answer:

Carbohydrates are broken down into glucose via glycolysis, into 2 molecules of pyruvate. From here, pyruvate can undergo aerobic respiration to generate energy (the TCA route). Pyruvate will undergo a series of oxidation and chemical reactions to ultimately generate ATP for the electron transport chain.

Question:

What is one way to ensure softer and more chewy cookies?

Savanna G.
Answer:

Use shortening over butter. Since shortening melts at a higher temperature than butter, this will give batter time to rise and retain moisture. Use a little brown sugar in place of white; the molasses that give brown sugar its color love moisture and will produce a more chewy cookie. Use baking powder over baking soda. This ensures that the cookie will spreads less over the pan, since powder is more acidic than soda. The thinner the cookie, the greater the moisture loss.
