animals eat the plants‚ and take the carbon in the sugars‚ inside their cells they take the energy from the food‚ this is cellular respiration‚ which takes oxygen (product of photosynthesis) and makes carbon dioxide (also used in photosynthesis) ‚ it then gives energy by breaking down the food molecules‚ this is the link between the two. There are two types of cellular respiration; aerobic and anaerobic. Both use the same steps‚ where the sugar created during photosynthesis is broken down. (Audesirk

What are the 4 most important elements in the human body? C‚ O‚ N‚ H 4. Draw the periodic square for Helium. How many valence electrons does it have? How do you figure this out using the periodic table? Two valence e-‚ 23He‚ all the way right full shell only holds two electrons 5. What is an isotope? How are they used

Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and producing a high amount of ATP‚ but when in bread dough the

Associate Program Material – Heather Earnhardt Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

Photosynthesis “deposits” energy‚ used carbon dioxide and water‚ and produces oxygen and glucose. By cellular contrast‚ cellular respiration “withdraws” energy‚ uses oxygen and glucose and produces carbon dioxide and water. b. The chemical energy of glucose

Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy‚ it is also called an aerobic process‚ which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy from organic fuel

the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant)‚ Snail‚ and Goldfish‚ by measuring carbon dioxide production. Because ectothermic organisms (Elodea‚ snail‚ and goldfish) were placed in completely covered beaker‚ each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms‚ and to determine and compare the rate of cellular respiration in each organism.
