the outside and inside of the membrane. Without a gradient of protons the majority of the ATP produced by cellular respiration couldn ’t be produced which is essential to make fatty acids and breakdown glucose‚ therefore the energy in a persons metabolism comes from stored fat or protein‚ causing a person to lose weight as well as causing a lack of energy. In the same sense the body must find another source of energy to give the body enough ATP to survive‚ unfortunately in the DNP case it lead to

rate does not depend on the temperature of their surroundings‚ and they can be as active on a cold winter’s night as they are on a hot summer’s day. Reptiles such as toads are sometimes described as “cold-blooded” because they do not use their metabolism extensively to control their body temperature. However‚ they do regulate their body temperature by using behavioral adaptations. A more accurate description of these reptiles is to say that they are ectothermic‚ which means that they absorb external

the following terms. Remember - you can’t use the word you are defining in its definition! 1. Homeostasis – The ability of an organism or cell to maintain the same internal environment regardless of changes in the external environment. 2. Metabolism –The chemical reaction that occur in a cell. 3. Experiment –Procedures used to test a hypothesis. 4. Control group – Subject(s) that goes through the steps of the experiment but is not exposed to or lacks the element being tested. Used

endocrine organs have a great deal of influence over the body. Among their many jobs are regulating the body’s growth and development‚ controlling the function of various tissues‚ supporting pregnancy and other reproductive functions‚ and regulating metabolism. Endocrine organs are sometimes called ductless glands because they have no ducts connecting them to specific body parts. The hormones they secrete are released directly into the bloodstream. In contrast‚ the exocrine glands‚ such as the sweat

Temperature (growth condition): Optimum growth conditions: -the temperature at which a microorganism’s metabolic activities produce the highest growth rate. Minimum growth conditions: -the lowest temperature at which an organism is able to conduct metabolism. Maximum growth conditions: -the highest temperature at which an organism continues to metabolize. Distinguish among mesophiles‚ thermophiles‚ hyperthermophiles‚ psychrophiles‚ psychrotrophs‚ acidophiles‚ alkalophiles‚ neutrophiles‚

form to another. All living organisms have a constant energy requirement; therefore‚ they have biochemical mechanisms that allow them to gather‚ store‚ and use energy. These mechanisms are collectively known as metabolism. A sequence of reactions must occur with each mechanism of metabolism‚ forming metabolic pathways. When we study photosynthesis in next week’s lab‚ you will investigate the metabolic pathways in which green plants capture light energy to produce the carbohydrate known as glucose

2. Because of the different organs that were removed from the two other rats that would produce certain hormones. My prediction was correct. 3. Thyroxine would be missing in its blood. 4. Thyroxine wouldn’t be released which helps maintain metabolism and body. The hormone levels would be lower as a result. 5. The metabolic rate went up.My prediction was correct. 6. It raised the rate‚ even though it wasn’t as high as the normal rat’s‚ it was still hyperthyroidic. The dose was too large

All living things can be categorize into one of six kingdoms‚ and they share five basic properties. All living organisms share common characteristics‚ and they share five basic properties. They are: cellular organization‚ metabolism‚ homeostasis‚ growth and reproduction‚ and heredity. (Johnson‚ 2010‚ p. 15) Those living things are categorized into six groups called Kingdoms. The six kingdoms are Bacteria‚ Archaea‚ Protista‚ Fungi‚ Plantae‚ and Animalia. Viruses do not belong to the above
