1.) what is the optimal pH for pepsin? where is pepsin found?
2.) what is the optimal pH for salivary amylase? what substrate does it act on? where is it found?
Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0
The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2. The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8. around 7
Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

Solar Energy Supply Part 4 0.0/5.0 puntos (calificado) Now let's look at the land needed for solar to supply all the energy needs of the USA. Since the electricity can be used with nearly 100% efficie
land needed for solar to supply all the energy needs of the USA is Energy production / 20 W/ft².
To determine the land needed for solar energy to supply all the energy needs of the USA, we need to consider the total energy consumption of the country and the efficiency of solar panels.
The energy consumption of the USA varies over time, but according to the U.S. Energy Information Administration (EIA), the total primary energy consumption in 2020 was approximately 92.94 quadrillion British thermal units (Btu).
To convert the energy consumption into the energy produced by solar panels, we need to consider the efficiency of solar panels. The efficiency of solar panels can vary, but let's assume an average efficiency of 20%. This means that solar panels can convert 20% of the sunlight they receive into usable electricity.
Now, we can calculate the energy production from solar panels:
Energy production = Energy consumption / Solar panel efficiency
Energy production = 92.94 quadrillion Btu / 20%
To convert the energy production into the area of land needed, we need to consider the average energy production per unit area of solar panels. The average energy production of solar panels can vary based on factors such as location, sunlight intensity, and panel technology. Let's assume an average energy production of 20 watts per square foot (W/ft²).
Now, we can calculate the land needed:
Land needed = Energy production / Average energy production per unit area
Land needed = Energy production / 20 W/ft²
The resulting value will be in square feet (ft²), representing the land area needed for solar panels to supply all the energy needs of the USA.
It's important to note that this calculation provides a general estimation based on the given assumptions of energy consumption, solar panel efficiency, and average energy production per unit area. The actual land needed may vary depending on specific factors and technological advancements in the future.

Essay - What is the damage the ecology of a lake obtains when items
are put in it that aren’t supposed to be there?
The ecology of a lake obtains considerable damage when items are put in it that aren’t supposed to be there. Human activities like agricultural runoff, dumping of industrial waste, and sewage treatment contribute to the pollution of freshwater bodies. It affects aquatic life and the ecological balance of the lake by disrupting the food chain and natural processes.
An ecosystem refers to a natural system of living things and their surroundings. A lake ecosystem includes various living organisms such as fish, plankton, algae, and many other aquatic species. Additionally, it comprises non-living things such as water, minerals, nutrients, etc. Any human-made or synthetic material that enters the lake upsets this natural balance. When harmful chemicals such as pesticides and fertilizers are used on agricultural fields, they contaminate the water and increase the nutrient content of the lake.
It encourages the growth of algae and other aquatic plants that use up oxygen in the water. When they decompose, they further reduce oxygen levels, which results in suffocation and death of aquatic organisms.Dumping of industrial waste is another human activity that contributes to the pollution of freshwater bodies. Chemicals like lead, mercury, and arsenic are toxic and can cause severe damage to the aquatic ecosystem. Fish and other aquatic animals may ingest these toxins and can accumulate them in their body tissues.
It results in reduced growth, deformities, and death of these animals. Sewage treatment is essential in cities to ensure that wastewater is treated and released into natural water bodies. However, inadequate or improper treatment can lead to a considerable increase in nutrients and organic matter in the lake, leading to harmful algal blooms and fish kills. In conclusion, human activities have significantly damaged freshwater ecosystems, and steps must be taken to reduce pollution to save these vital resources.

explain how carbon atoms can move to co2 in the air into an organic molecule inside a plant and then back to co2 in the air
Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.
