stop! and get a stamp.
experiment design
smithers thinks that a special juice will increase the productivity of workers. he creates two groups of 50 workers each and assigns each group the same task (in this case, theyre supposed to staple a set of papers). group a is given the special juice to drink while they work. group b is not given the special juice. after an hour, smithers counts how many stacks of papers each group has made. group a made 1,587 stacks, group b made 2,113 stacks.
identify the:

1. control group: _______________
2. experimental group: _______________
3. independent variable: _______________
4. dependent variable _______________
5. constants: _______________

Question 2 (Cellular Respiration Process)

Step1: Glycolysis

Glucose (input) is broken down in the cytoplasm into pyruvate, producing a small amount of ATP and NADH.

Step2: Pyruvate Oxidation

Pyruvate (input from glycolysis) enters mitochondria, is oxidized to acetyl - CoA, releasing CO₂ and producing NADH.

Step3: Citric Acid Cycle

Acetyl - CoA (input) combines with oxaloacetate in the mitochondrial matrix. Through a series of reactions, CO₂ (output), ATP, NADH, and FADH₂ are produced.

Step4: Electron Transport Chain (ETC)

NADH and FADH₂ (inputs) donate electrons to the ETC in the inner mitochondrial membrane. O₂ (input) is the final electron acceptor, forming H₂O (output). The energy from electron transfer is used to pump H⁺, and the flow of H⁺ back through ATP synthase produces a large amount of ATP (output).

Cellular respiration is the process by which cells break down glucose (and other organic molecules) in the presence of oxygen, through glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain, to produce ATP (energy), carbon dioxide, and water.

Photosynthesis (in plants, algae, and some bacteria) uses carbon dioxide and water, in the presence of light energy, to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and ATP. The oxygen and glucose produced by photosynthesis are the inputs for cellular respiration, and the carbon dioxide and water produced by cellular respiration are the inputs for photosynthesis. They are complementary processes that recycle carbon, oxygen, and energy in the biosphere.

Answer:

Cellular respiration starts with glycolysis in the cytoplasm, where glucose is broken down into pyruvate (outputs: pyruvate, small ATP, NADH). Pyruvate then enters the mitochondria and is oxidized to acetyl - CoA (output: CO₂, NADH). The citric acid cycle in the mitochondrial matrix uses acetyl - CoA, producing CO₂, ATP, NADH, and FADH₂. Finally, the electron transport chain in the inner mitochondrial membrane uses NADH, FADH₂, and O₂ to produce a large amount of ATP and H₂O. Inputs: glucose, O₂; Outputs: CO₂, H₂O, ATP.
