What are the steps in the cycle of rock formation?
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
What is the first stage of the rock cycle?
The rock cycle begins with molten rock (magma below ground, lava above ground), which cools and hardens to form igneous rock. Exposure to weathering and erosional forces, break the original rock into smaller pieces.
What are the different stages of the Calvin cycle?
The Calvin cycle diagram below shows the different stages of Calvin Cycle or C3 cycle that include carbon fixation, reduction, and regeneration. Calvin cycle or C3 cycle can be divided into three main stages:
What is the rock cycle and how are rocks formed?
The Rock Cycle. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
How many glucose molecules are formed in the Calvin cycle?
One molecule of carbon is fixed at each turn of the Calvin cycle. One molecule of glyceraldehyde-3 phosphate is created in three turns of the Calvin cycle. Two molecules of glyceraldehyde-3 phosphate combine together to form one glucose molecule.
How many turns does the Calvin cycle take to fix CO2?
In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO2.
