- Simple systems (of this type) of RNA , enzymes, and coenzymes have been created in the laboratory. Which probable stage of physical and chemical evolution of life is that.arrow_forwardHow could you use the diversity of metabolic pathways that produce the same or similar products to critique this argument? Rank the steps from first to last. a. New enzymes cause modification of the pathway in an advantageous way. b. The biochemical pathway is gradually modified. c. A pathway exists and accomplishes some functions. d. An organism with cellular enzymes has mutations that allow new enzymes to arise.arrow_forwardApproximately how long ago did homo sapen (humans) first appear on Earth 2,000 years ago 5-7 million years ago 65 million years ago 150,000 - 200,000 years ago Hominins developed their unique larger brains before acquiring the ability to move on two feet. True False the production of atmospheric oxygen in Earth's environment started with photosynthesis by prokaryotes photosynthesis by multicellular eukaryotes photosynthesis by single celled algae photosynthesis by land plants Homologous structures among animal provide evidence for evolution in that theses structure are all produced by the same gene different in different animals, but are modifications of the same basic structure similar in function, but of different basic structure all different structures within the same speciesarrow_forward

- Why protiens are called the shapers of life?arrow_forwardcreate a single illustration that will interrelate or link the two opposing pathways, the Glycogenesis and Glycogenolysis. I want you to include the enzyme in each step and include some important by-products as well. From the illustration, I want you to encircle the intermediate molecule to highlight the link between the two processes. Aside from the illustration, I want you to compare and contrast the two pathways in terms of function, number of reaction steps, and usage of UTP. You can tabulate this part to make it simpler.arrow_forwardWhen energy is transferred from one organism to another, some energy is lost to the environment due primarily to ____ ?
