The results related to the activity of Na + /K + -ATPase (sodium/potassium adenosine triphosphatase) in the gills of the fish exposed to aluminum and its comparison with the control fish. Introduction: The Na + /K + - ATPase is the enzyme, which works as a pump, and is found in the plasma membrane of the cell. Its function is to allow the movement of sodium ions out of the cell and potassium ions into the cell. Scientists exposed freshwater bony fish ( Prochilodus lineatus ) exposed to water with high aluminum level and another set of fish that was exposed to water with normal aluminum levels (control). The results of the data are shown in graph below:

In this experiment, you will be monitoring changes in CO2 concentration due to aerobic respiration and photosynthesis of each test organism. Which of the following results would be expected from the conditions described? Remember this is a closed system (the CO2 cannot escape), and we are monitoring changes in CO2 concentration over a 3 minute period. A) An animal will produce a higher increase in CO2 when exposed to the light than when kept in the dark. B) A plant will cause an overall higher increase in C02 concentration when exposed to light versus an plant kept in the dark. C) A plant will cause an overall higher increase of CO2 concentration when kept in the dark versus a plant exposed to light. D) An animal will show a decrease in CO2 while kept in the dark and an increase in CO2 while in the light.

Palytoxin is a deadly compound found in certain marine animals. When scientists first isolated palytoxin from sea corals in the 1970s, they did not know how it affected people exposed to it. In time, they began to suspect that the toxin was interfering with the sodium-potassium pump. Researchers have measured the effect of palytoxin on ion transport through the sodium-potassium pump using the patch-clamp technique. This involves using a fine-tipped microelectrode to measure the electric current across pumps in the cell membrane. In this activity, you will examine some of the researchers' results and conclusions. Procedure 1. Read the following observations that researchers made after adding palytoxin to a membrane, and then answer the questions. • Observation 1: The current across a single pump jumped from 0 picoamperes to 1 picoamperes. • Observation 2: When ATP was added to the cytoplasm-facing side of the membrane, the current across a group of pumps increased by a factor of 8…
