Ques: Answer the following question given this paragraph: Gastric Secretion The secretion of gastric juice is controlled by both nerves and hormones. Stimuli in the brain, stomach, and small intestine activate or inhibit gastric juice production. This is why the three phases of gastric secretion are called the cephalic, gastric, and intestinal phases (Figure 23.17). However, once gastric secretion begins, all three phases can occur simultaneously. Q: Stimuli in the brain, stomach, and small intestine activate or inhibit production of what secretion?

(Q).
Answer the following question given this paragraph: The pyruvate molecules from glycolysis next enter the matrix of a mitochondrion. That's where the second stage of cellular respiration takes place. This stage is called the Krebs cycle . During this stage, two more molecules of ATP are produced. Other energy-storing molecules are also produced (to be used to make more ATP in stage 3). The Krebs cycle requires oxygen. Anything that needs oxygen is described as aerobic . The oxygen combines with the carbon from the pyruvate molecules. This forms carbon dioxide, a waste product. Q: What is the second stage of cellular respiration? Choices: - beatnik cycle - duocycle - marr cycle - krebs cycle A:
(A).
krebs cycle
