Animals can only do respiration; they cannot perform photosynthesis. Plants can perform photosynthesis, but cannot do respiration. True False One way or another, nearly all the carbon in the bodies of plants and animals ends up back in the atmosphere as carbon dioxide. True False If humans did not start digging up and burning fossil fuels about 200 years ago, the total amount of atmospheric carbon would have remained roughly the same. True False When one burns a hydrocarbon like...
How Do Chloroplasts Capture Energy from the Sun? Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from sunlight, a process known as photosynthesis. Specialized pigments in the chloroplast absorb sunlight and use this energy combine carbon dioxide and water to make glucose and oxygen. The complete reaction is: 6CO2 + 6H2O + C6H12O6 + 6O2 Raw Materials (Reactants) CO2 = carbon dioxide H2O = water Products C6H1206 = glucose O2 = oxygen Plant cells can...
27) Which one of the following best describes the electron transport chain? A) Electrons are passed from one carrier to another releasing a little energy at each B) Hydrogen atoms are added to CO2 to make an energy-rich compound. C) Electrons are pumped across a membrane by active transport. D) Glucose is broken down to a three-carbon compound 28) After completion of the citric acid cycle, most of the usable energy from the one molecule is in the form of...

A) what is the relationship between photosynthesis and cell respiration? 1. photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back. 2. photosynthesis releases oxygen into the admosphere, and cellular respiration uses that oxygen to release energy from food. B) what color found in many plants is produced by which pigment? C)what color of light are green plants the best at reflecting? 1. yellow 2. green 3. blue. 4 red D) what are the two main sets...

True or false and can you please help explain why. 1. a. An individual eats a sweet potato, which is a food containing high amounts of maltose. For each maltose molecule ingested, a cell produces 32 net ATP. b. In a person with a respiratory system disorder such as emphysema, carbon dioxide accumulates in the blood and becomes toxic. c. Plants can create a variety of macromolecules (carbs, proteins, lipids) from G3P. d. glyceraldehyde 3-phosphate is an intermediary in both photosynthesis...
An extremely important process is called "CARBON FIXATION' What is carbon fixation? This is where plants incorporate CO_2 into organic compounds-the base of our food web This is where plants strip electrons from organic food molecules This is the stage in photosynthesis where glucose appears This is the stage in Calvin cycle where ribulose bisphosphate is regenerated, ready for a new cycle This is where photosynthetic species are eaten, moving their energy into the food web Plants couple tow photosystems...
What are the N. Circle the at are the products of the Calvin cycle? ircle the letter of each statement that is true about the Calvin cycle. Correct the false statements. The main products of the Calvin cycle are six carbon dioxide molecules. b. Carbon dioxide molecules enter the Calvin cycle from the atmosphere. C. Energy from ATP and high-energy electrons from NADPH are used to convert 3-carbon molecules into similar 3-carbon molecules. d. Calvin cycle uses six molecules of...
