Enzymes, digestion, and ATP Review

Master enzymes, digestion, and ATP! Learn digestive organs, enzyme roles, and the ATP cycle for biology success.

Test Objectives 1) Know the functions of the digestive system.2) Know the location and function of each organ in the digestive system.3) Know how enzymes assist in the process of digestion, why there are so many, and how they maintain homeostasis in the body.4) Know the two types of enzymatic action (induced fit and lock and the role of coenzymes.5) Know what ATP is, how energy is released from it, and how the ATP cycle works and the role of hydrolysis in that cycle. Induced Fit vs. Lock and Key Complete the Venn diagram to compare and contrast these two enzymatic processes. Use as many spaces as you need. Lock and Key Both Induced Fit Enzyme Questions Answer the following questions on enzymes:1) What role to enzymes play in digestion?2) What are co-enzymes and why do they exist?3) Why are there so many different kinds of enzymes in the body? Couldn't we just have one? (catalase, amylase, lipase, protease, etc) ATP Cycle Fill in the missing components of the chart below. ATP ADP ATP Cycle Answer the following questions:1) What is the role of ATP in the body?2) Explain what is happening in the image that you labeled in the prior question.3) How does hydrolysis play a role in that cycle?4) What is the difference between products and reactants? Digestive System Labeling Use the following terms to label the digestive system: stomach, esophagus, liver, small intestine, large intestine, pancreas, gall bladder, salivary glands, and oral cavity. salivary glands oral cavity esophagus liver small intestine stomach gall bladder large intestine pancreas Digestive System Definitions 1) A type of exocrine gland that secretes enzymes to lubricate and break down food. Answer: Salivary Glands2) The membrane-lined cavity behind the nose and mouth, connecting them to the esophagus. Answer: Pharynx3) The tube that performs muscular contractions called peristalsis to move food down to the stomach. Answer: Esophagus4) The sac like structure that functions both as a mechanical and chemical digestion. Answer: Stomach5) The narrow tube approximately 21 feet in length that is responsible for 90% of all nutrient absorption. Answer: Small Intestine6) This is a wider tube that reabsorbs water, contains colonies of digestive bacteria, and produces feces. Answer: Large Intestine7) Bile is produced and stored here. Answer: Gall Bladder8) The organ that has both digestive and endocrine functions and releases enzymes for nutrient digestion. Answer: Pancreas9) This large organ performs essential functions related to digestion, metabolism, immunity and the storage of nutrients in the body. Answer: Liver10) The location where mastication happens and mechanical digestion begins. Answer: Oral Cavity. Final Question How do digestion, enzymes, cellular respiration, food and ATP all work together to power the body? Make sure to be specific in your response. Assume we have no idea how the body works.
