Permeation Glycolysis differs from the other steps of cellular respiration because A. Glycolysis requires oxygen B. Glycolysis can only use sugar as a substrate C. Glycolysis occurs in the cytoplasm, instead of in the mitochondria D. Glycolysis does not need enzymes to function 99. To be scientifically valid, a hypothesis must be A. Phrased as a question B. Reasonable C. Testable and falsifiable D. Based on Faith 100. In cells containand proteins. They are manufactured in the , a specialized region of the nucleus. A. DNA, chromatin, chromosome B. Ribosomes, rRNA, nucleolus C. Membranes, sugars, endoplasmie reticulum D. Mitochondria, enzymes, chromosome 101. Which of the following is the best metaphor for describing the relationship between an enzyme and its substrate? A. A lock and a key B. A pot and its lid C. Two ropes tied together D. Two magnets 102. You are researching a certain pigment found in the eye. This pigment is the product of just one gene. You find that there are two alleles for eye color: one form produces golden color, and the other produces blue color. In heterozygous individuals, they make both pigments and the resulting eye color is green. What type of inheritance pattern have you found? A. Complete dominance B. Multiple alleles C. Codominance D. Polygenic inheritanceExplanation / Answer
97. A. Diffusion movement of compounds from high to low concentration until equilibrium is reached.
98. C. Glycolysis occurs in the cytoplasm, instead of in the mitochondria. Oxidative decarboxylation of pyruvate, Citric acid cycle and oxidative phosphorylation occur in mitochondria.
99. C. Testable and falsifiable. Hypothesis is a tentative, reasonable and testable answer to a scientific question.
100. B. Ribosomes, rRNA, nucleolus
101. A. A lock and a key. Enzyme is like a lock and substrate is its key.
102. C. Codominance both the genes are dominant.
