- Below are the results of an experiment to examine the effect of temperature on metabolic rate in mice. Metabolic Rate in Mice at 10°C and 22°C 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 10 degrees C 22 degrees C Chamber Temperature (°C) What is the dependent variable in the experiment? What is the independent variable in this experiment? What is the relationship between temperature and metabolic rate? Metabolic rate (cal/gram/min)The image shows the electron transport chain and ATP synthesis during cellular respiration within a eukaryotic cell. The reaction shows the conversion of glucose into ATP and heat during eukaryotic cellular respiration. Which of the following is true regarding specialized cellular respiration occurring in newborns and hibernating mammals to maintain body temperature? Additional molecules of glucose are oxidized to generate the additional body heat required for human infants and hibernating mammals. The cellular efficiency of ATP synthesis increases to generate the additional body heat required for human infants and hibernating mammals. The cellular efficiency of the electron transport chain increases to generate the additional body heat required for human infants and hibernating mammals. The electron transport chain and proton gradient efficiency are maintained without ATP synthesis to generate the additional body heat required for human infants and hibernating mammals.Table 8.2.

Put a dot on the graph in Figure 8.11 for each of the average values. Draw a line between those two dots. Write the word ectotherm on the line.
- What is the structure of the following abstract? Answers are sentence by sentence with punctuation preserved. Ageing is an irreversible cellular decline partly driven by failing mitochondrial integrity. Mitochondria accumulate DNA mutations and reduce ATP production necessary for cellular metabolism. This is associated with inflammation. Near-infrared exposure increases retinal ATP in old mice via cytochrome c oxidase absorption and reduces inflammation. Here, we expose fruitflies daily to 670 nm radiation, revealing elevated ATP and reduced inflammation with age. Critically, there was a significant increase in average lifespan: 100–175% more flies survived into old age following 670 nm exposure and these had significantly improved mobility. This may be a simple route to extending lifespan and improving function in old age. B=Background Q=Question A=Approach R=Result L=Literal Interpretation S=Speculative interpretation Q. B. B. B. R,L.

Dependent: _________________________________________________________ Independent: ________________________________________________________ List 2 other variables would need to be controlled in the experiment. 1. 2.Study the diagram above. (You might also want to do a little research.) Write (this is an essay style assignment) a WELL THOUGHT OUT response comparing and contrasting the energy conversion (combustion) process that occurs in an automobile with the energy conversion process (cellular respiration) that takes place in your cells. Please make sure that you are using your own words, and not copying and pasting words from other sources. PROVIDE YOUR RESOURCES for any borrowed information. Your writing MUST include the following thought process: How can the two processes (combustion and cellular respiration) end up with the same products, but start out with different reactants?
- A(n) [Select ] 7 organism can maintain a constant temperature using its metabolic heat while a(n) v [ Select ] Forganism will use environmental temperatures to do so. heterothermic ectothermic homeothermic endothermicIn hepatocytes, the enzyme glucokinase catalyzes the ATP-coupled phosphorylation of glucose. Glucokinase binds both ATP and glucose, forming a glucose-ATP-enzyme complex. The enzyme then transfers the phosphoryl group directly from ATP to glucose. Select the advantages of phosphoryl group transfer compared to hydrolysis and subsequent phosphorylation? Glucokinase increases the transition state energy, favoring glucose phosphorylation. Reaction intermediates do not need to be present in excess. The process takes advantage of the high phosphoryl group transfer potential of ATP. ATP hydrolysis is thermodynamically unfavorable compared to group transfer.When hunting disrupts balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers. Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following the table in no. 1 (Sun + E = 6) and answer the following questions:
- This question is only semi-random, it does relate to something said in the video. You must supply energy to start combustion reactions: you must drag a match across a rough surface to get it to light, the heat from a lit match or lighter is required to start charcoal burning, gas stoves often use an electric spark to ignite the methane (natural gas), etc. The fact that you must supply energy to get these reactions started is evidence of activation energy specific heat exoothermic reactionWhich of the following is true regarding the metabolism in animals? O Metabolism is the total chemical activity, which is the sum of all anabolic and catabolic processes. O The Anabolic Pathways serve to break down molecules while the Catabolic Pathways synthesize important chemical building blocks. Through respiration, organisms obtain oxygen, whose rate is inversely porportional with the metabolic rate. O Metabolic Rate is not influenced by an organism's body temperature. O Poikilotherm organisms do not have any effect in body temerature when their enviornment temperature changes.Consider the following graph with metabolic rate on the left y-axis (grey line) and mass-specific metabolic rate on the right y-axis (black line): Elephant 10,000 Horse 10,000 Human 1,000 1,000 Dog Rabbit 100 100 White rat 10 10 White mouse 0.1 1.0 10 100 1,000 Body Mass (kg) kcal/day kcal/kg/day (metabolic rate)
