Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule‚ such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates‚ proteins‚ and fats can all be metabolized as fuel‚ but cellular respiration is most often described as the oxidation of glucose‚ as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories

Describe by which gland/location/target which cells. Explain steroid and non-steroid hormones. Some endocrine glands are specialist that primarily secrete hormones into blood‚ such as the thyroid. Some serve as dual roles by

Lab on pH Levels Purpose: Throughout this experiment we are trying to learn how to take proper pH measurements using a pH meter. We also want to see the pH of different common liquids and record the change in pH when we add acids and alkaline liquids. The last reason we are conducting this experiment is to explain and show how fresh milk spoils by the change in pH. Materials: In this experiment we used graduated cylinders and glass beakers and added variety of ingredients including 50 mL of; soda

1. During the install‚ the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective‚ why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a server’s notion of time in

Graph 1‚ illustrates the pH of each quadrat. The pH in Quadrat 1 was more acidic than the pH in Quadrat 2‚ 3‚ and 4 this is due to the slope of the ground (refer to Graph 8)‚ different soil substrate and the decomposition of organic matter. As can be seen from Graph 8‚ the soil pH increased with a decrease in the slope of the ground. In Quadrat 1‚ the soil had a pH of 7.5 due to having a higher soil elevation of -8° in comparison to Quadrat 2‚ 3 and 4‚ in which the slope of the ground was -2°‚ -2°

Life cycle of a star Every star has a life cycle just like a human or a frog except stars do it on a much larger scale. Stars start life as a massive cloud of matter and then get pulled together to create a star. But stars do not last forever most stars last for millions of years but they still end. When a stars life ends it may explode or implode to create a black hole. The reason stars even start life and end life is because of nuclear fusion. Nuclear fusion is a reaction where matter is forced

NaCl ‚ Urea ‚ Glucose Which did not ? Albumin Why ? Albumin’s Composition or charge was too great to diffuse through the membrane. After the 2nd activity : Simulating Dialysis What happens to the urea concentration in the left beaker (the Patient)? It diffused to the right beaker Why does this occur? The excess
