		Give a full, detailed answer to the task in Part 2. 34. What organisms are classified as autotrophs? What groups are autotrophs divided into based on the way they use energy? Give examples of organisms from each group. Autotrophs are organisms capable of synthesizing organic substances from inorganic substances. Organisms that use an inorganic carbon source to synthesize organic molecules. Photoautotrophs use energy sunlight for photosynthesis. These include plants and photosynthetic bacteria. Chemoautotrophs use the energy of oxidation of inorganic substances. These include, for example, nitrifying bacteria, iron bacteria, sulfur bacteria, and hydrogen bacteria. 35. What phases are distinguished in photosynthesis? What processes occur during these phases? Write down the general formula for photosynthesis In photosynthesis, there are light and dark phases. In the light phase, photolysis of water occurs due to light energy with the formation of ATP and NADPH 2 , and oxygen is released. In the dark phase, in the reactions of the Calvin cycle, organic substances are formed from carbon dioxide and NADP H 2 due to the energy of ATP. General formula of photosynthesis: 6CO 2 + 6H 2 O + light energy → C 6 H 12 O 6 + 6 O 2 36. Explain what processes in the light phase of photosynthesis lead to the formation of NADPH 2 , ATP and oxygen release. The energy of light photons is captured by the electrons of the chlorophyll molecule and the excited electrons leave the molecule. When passing through the electron transport chain, their excess energy is used to replenish the proton reservoir of the thylakoid and form NADPH 2 ; The chlorophyll molecule is restored with the help of a special enzyme that takes electrons from water, and the water molecules decompose to form oxygen and protons; Protons accumulating in the thylakoid cavity pass through the ATP synthetase channel, and their energy is used to form ATP. 37. Find errors in the given text: 1. Plants are photosynthetic autotrophs. 2. Autotrophic organisms are capable of synthesizing organic substances from inorganic compounds. 4. In the dark phase of photosynthesis, starch molecules are formed. 5. During the process of photosynthesis, light energy is converted into the energy of chemical bonds of organic compounds. 38. The process of photosynthesis occurs intensively in the leaves of plants. Does it occur in ripe and unripe fruits? Explain your answer. 1) Photosynthesis occurs in unripe fruits (while they are green), because they contain chloroplasts. 2) As they mature, chloroplasts turn into chromoplasts, in which photosynthesis does not occur 39. What is the role of mitochondria in metabolism? Which tissue, muscle or connective tissue, contains more mitochondria? Explain why. 1) mitochondria - cell organelles in which intracellular oxidation of organic substances (respiration) occurs with the formation of hydrogen 2 O and CO 2 2) is formed large number ATP molecules that are used in the life of cells and the body as a whole 3) muscle tissue contains more mitochondria, because muscle contraction requires a large amount of energy Metabolism and Energy Test 22.01.2015 14768 0 1.What is plastic exchange?
