Pepsin and trypsin are two digestive enzymes. One enzyme is found in the stomach the small intestine. Use the graph below to answer the questions below and the other is in a. Which enzyme is found in the stomach?-pepsin- b. What is the optimum pH for each enzyme to function properly?

Humans depend on plants for carbon dioxide and organic carbon (glucose). Thylakoid membranes are found in mitochondria. During photosynthesis, electrons always go through the light-dependent reactions before entering the Krebs cycle. The amount of ATP produced from one glucose molecule during aerobic respiration is thirty six Carbons from the breakdown of glucose are lost during the TCA cycle as carbon monoxide. Glucose is reduced during aerobic respiration. Feedback inhibition involves the inhibitor binding the enzyme’s active site. In photosynthesis, the light reactions produce ADP and NAD+ for the synthesis reactions Electron transport chain in aerobic respiration takes place in the matrix.

The product of glycolysis is and it is converted into as it enters the to begin the Krebs cycle. 2. The two processes by which ATP can be made during respi oxidative ration is called substrate-level and 3. The light reactions ocur on the er and the Calvin cycle occurs in of the 4. Physical factors such as heat and pH proteins. 5. To synthesize one glucose molecule, the Calvin cycle uses six molecules of eighteen molecules of 6. Respiration is a and twelve molecules of NADPH. process and photosynthesis is a procesS reactions of photosynthesis. 7. Water molecules are split during the 8. Two important electron carriers during respiration are 6. Label the diagram for photosynthesis using the following terms. NOTE: The arrows are used for some, (4 pts) but all of the terms. You may need to include your OWN arrows to complete the diagram.

Compare and contrast five types of transport – osmosis, simple diffusion, facilitated diffusion, active transport and bulk transport. (10 pts)
