(note: some textbooks state that up to 36 atp molecules are produced in this phase of cellular respiration. in reality, some energy is lost in the process due to the cost of transporting molecules and imperfect membranes.)

extend your thinking: when you think of the word “respiration,” you might think about the process of breathing, which is actually called ventilation. (the respiratory system consists of the windpipe, lungs, etc.)
how is breathing related to cellular respiration? (hint: think about both the inputs and the outputs of cellular respiration.)

Drag each label to the correct location on the table. each label can be used more than once. decide whether each statement describes saturated fat, unsaturated fat, or both saturated and unsaturated fats.

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
