NADPH. The occurrences of light-dependent reactions happen within the THYLAKOIDS of the chloroplasts. The substances consumed during this reaction is light‚ which is absorbed by chlorophyll molecules‚ which then produces hydrogen ions‚ electrons‚ oxygen gas‚ ATP and NADPH. “The light-dependent reactions drive the light-independent reactions‚ which means the products of the light-dependent reactions‚ ATP and NADPH‚ are required for the light-independent reactions to proceed.” (Photosynthesis Lab

during aerobic respiration (respiration that uses oxygen) chemical reactions occur that: * use glucose (a sugar) and oxygen * release energy. * c) Know and understand that aerobic respiration takes place continuously in both plants and animals. * d) Know that most of the reactions in aerobic respiration take place inside mitochondria. * e) Know that aerobic respiration is summarised by the equation: * glucose + oxygen ==> carbon dioxide + water (+ energy) * f)

RESPIRATORY SYSTEM OBJECTIVE QUESTION 1) High-flying birds are able to obtain enough oxygen even when the air is very thin because A) they have more efficient lungs than other vertebrates. B) they have reduced amounts of hemoglobin in their blood. C) their mitochondria are more efficient than those of other vertebrates. D) their heart can increase or decrease in size as altitude changes. E) they are able to store oxygen in oxygen chambers within muscle cells. 2) If you were to move from around sea level to

with no oxygen. 5) The oceans formed when the water vapour condensed. Phase 2- Green plants evolved and produced oxygen. 1) A lot of CO2 dissolved into the oceans. 2) Marine organisms developed which took some of this CO2. When they died the organisms were buried under layer of sediments and the CO2 became “locked up” in carbonate rocks. 3) Green plants evolve over most of the Earth. 4) Green plants removed CO2 from the air and produced O2 by photosynthesis. (oxygen level increased)

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

respiration and burning use oxidation to release energy. In respiration‚ oxygen combines with glucose to release energy which can be used in the body. Also some heat is produced to keep the body warm. Burning normally occurs in oxygen (in form of O2) to form oxide. However‚ burning can take place in other gases such as chlorine. Also both of these reactions are exothermic - both reactions release heat after reacting with oxygen. Another similarity is that both reactions release energy after oxidation

occur easily. In larger organisms‚ for example animals‚ gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals‚ the exchange occurs directly with the environment. But with complex animals‚ such a mammals‚ the exchange occurs between the environment and the blood. The blood then carries oxygen to deeply embedded cells and transports carbon dioxide out to where it can be removed from the body.

and low level of oxygen at the summit. When they finally made it to the top‚ the two men cheered and embraced. Then Hillary did something to prove a point—he took off his oxygen mask. He wanted to show that a person could stay alive while breathing naturally at that high altitude. But after a few minutes‚ his vision began to fail. When Hillary replaced his mask‚ his vision improved. Then the two men started back down the mountain. Why did Hillary and Tenzing need to carry oxygen to the top of Mount

16‚ 2014 Anatomy and Physiology II Unit 5 Gas Exchange Explain how the gas laws and the properties of gases affect the gas exchange between the lung‚ blood‚ and tissues. The major function of the respiratory system is to provide the body with oxygen and rid the body of carbon dioxide. Gas exchange occurs between blood and alveolar air (external respiration) and between blood and tissues (internal respiration).Gas exchange process depends on properties of gasses. Based upon the Basic properties
