Cellular Digestion. For each of the following statements, indicate the specific digestion process or processes for which the statement is true: phagocytosis (P), receptor-mediated endocytosis (R), autophagy (A), or extracellular digestion (E). Each statement is true of one or more of these processes.
(a) Can involve exocytosis
(b) Can involve fusion of vesicles or vacuoles with a lysosome
(c) Digested material is of extracellular origin.
(d) Digested material is of intracellular origin.
(e) Essential for sperm penetration of the egg during fertilization
(f) Important for certain developmental processes
(g) Involves acid hydrolases
(h) Involves fusion of endocytic vesicles with an early endosome
(i) Involves fusion of lysosomes with the plasma membrane
(j) Occurs within lysosomes
(k) Serves as a source of nutrients within the cell

You are what you eat. What does this mean? If you eat only celery, will you become a vegetable? Sometimes there are so many words used to describe foods and nutrition, it is difficult to make sense of them. In fact, we do use the food we eat to provide energy and also the building blocks for growth and development. Even after you are fully-grown, your body, just like any other machine, needs to make constant repairs to injured areas and must replace cells that have died. To make sure that the structure of your body is correct and strong, you must provide it with a regular supply of the right building materials. Foods are the building materials for the body.
There are six large categories of nutrients in food. These are carbohydrates, protein, fats, vitamins, minerals, and water. Each food you eat not only contains more than one nutrient, but also a different number of calories (energy). Fat, protein, and carbohydrates provide calories, or energy as well as building blocks. Vitamins,…
Amino AcidMetabolism.
a. What are the SIXprecursors used in amino acid biosynthesis?
b. What are the SEVEN metabolic intermediates that result from amino acid degradation?
c. Circle the metabolites found in your answers to both a) & b) above.
d) What is the difference between glucogenic and ketogenic amino acids? List the glucogenic amino acids, the ketogenic amino acids & the amino acids that are both glucogenic & ketogenic.
The Big Picture " - Metabolic Integration. Metabolic pathways are regulated to maintain homeostasis in the face of changing environmental conditions, such as food supply. Explain how this is achieved during the fed-fast cycle using pathways important for three macronutrients (CHOs, lipids, protein). Also, specify the Signal(s) involved in the modulation of these paths.
