Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

Breast Cancer at the Cellular Level There are many different diseases that terrorize the human race every day. Of all of these sicknesses‚ one of the most devastating is breast cancer. Breast cancer touches all types of people all over the world each day. It is actually the second most common cancer amongst women in the United States. One in every eight women in the United States has some form of breast cancer and currently‚ the death rates are higher than any other cancer with the exception

produce a gas when sugar is available. For the third hypothesis‚ we did not expect yeast to produce a gas when no sugar or other food is available. The reason is that carbon dioxide is a product of respiration and is formed when the yeast respires. Therefore‚ when no food and sugar is available‚ respiration cannot take place. Hence‚ no carbon dioxide is formed.

There are many variables that could affect the rate of photosynthesis and the net consumption of carbon dioxide. In this experiment‚ the effects of how the intensity of light energy affected photosynthesis were observed. Two pieces of elodea was placed into separate beakers and one of the beakers was placed under a bulb of lower intensity and the other beaker being placed under a higher intensity bulb. The results showed that the beaker under the higher intensity light energy had a higher consumption

Title : Comparing the rates of pulmonary and cutaneous respiration in frogs Introduction Frogs are amphibians that live in moist environments to support one of their key mechanisms of respiration. Frogs have the ability to breathe many diverse ways‚ due to their unusual life cycle and aquatic and terrestrial environment. The Order Anura shows the extreme anatomical and physiological diversity. Many frogs use lungs to respire‚ bringing in air through their nares‚ mouth‚ into the trachea and then to

The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular

To understand that the lungs do not contain muscle and that respirations are therefore caused by external forces. To explore the effect of changing airway resistance on breathing. To study the effect of surfactant on lung function. To examine the factors that cause lung collapse. To understand the effects of
