Aerobic Respiration Breaking down glucose to release energy Products are Carbon dioxide and water Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal. Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

Gabriela Rios-Martinez March 1‚ 2014 BIO 141 Exam 1 Study Questions Chapter 1: Biology and the Tree of Life (#1 – 4) 1. What is the difference between a hypothesis and a scientific Theory? Between a hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world‚ and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. (a.) A scientific theory has two components; a pattern

Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating seeds and the glass

overall change in the height of the plant increased. This suggests a positive correlation. Plants require sunlight‚ water and carbon dioxide to grow. These are necessary in the process of photosynthesis‚ which makes glucose for the plants. The glucose is then used by the plant in the process of cellular respiration in order to make energy. 8. Conclusion:

Chapter 5 Assignment 1. What is energy? What are the three forms of energy? Energy is the capacity to do work. There are four types of energy according to the powerpoint. They are Kinetic energy (energy of motion)‚ potential energy (stored energy)‚ thermal energy (heat)‚ and chemical energy (potential energy of molecules). 2. State the First and Second Laws of Thermodynamics. Include entropy in your explanation. The first law states that energy can neither be created nor destroyed it can

we‚ and all other organisms‚ need to survive. It is produced primarily in the processes of aerobic and anaerobic respiration by oxidative and substrate phosphorylation. 4 molecules of ATP are produced from 4 ADP and 4 inorganic phosphates in glycolysis in the cytoplasm of every cell‚ by the oxidation of a triose phosphate into two molecules of pyruvate. In anaerobic respiration these are the only 4 ATP molecules produced per molecule of glucose as there is no oxygen available for the link

Chemoheterotrophic organisms obtain energy from the oxidation of organic compounds 7. What is photosynthesis and where does it take place? Photosynthesis is a process used by plants and other autotrophic organisms to convert light energy‚ normally from the sun‚ into chemical energy that can be used to fuel the organisms’ activities. Carbohydrates‚ such as sugars‚ are synthesized from carbon dioxide and water Photosynthesis is the means by which plants harvest light energy to make their own food it takes place

up with an explanation of what had just occurred‚ they felt a strong pull. This pull came from Cactus pear Opuntia Ficus-indica. Opuntia was ready to perform photosynthesis and nothing was going to stop her from using the friends of Carla and Carla. Without hope‚ Carla and her friends were unable to escape the cactus desires. Photosynthesis in Opuntia does not work the same way as in C3 plants because Opuntia is a CAM plant. Opuntia lives in a deserted region where it is hot and dry. Thus‚ Opuntia
