Does carbon dioxide molecules enter the Calvin from the atmosphere?
No, carbon dioxide molecules enter the Calvin cycle within the chloroplasts of plant cells. The stomata on the leaves allow carbon dioxide to diffuse into the leaf where it can be fixed into organic molecules during photosynthesis.
What tool will allow scientists to see patterns of carbon molecules?
Spectroscopy is a tool that allows scientists to identify the patterns of carbon molecules. By analyzing the absorption and emission of light at different wavelengths, scientists can determine the composition and structure of carbon molecules.
What element is the building block around which the molecules of life are built?
Carbon is the building block around which the molecules of life are built. It has versatile bonding properties that allow it to form a wide variety of complex organic molecules essential for biological processes.
What substances will a cell allow in?
A cell will only freely allow in very small molecules such as oxygen, water and carbon dioxide. Larger molecules such as sugars must be transported into the cell through special channels using energy.
Why almost all food sources are carbon based?
Organic chemistry is the study of carbon based molecules, and those types are excellent for life because they allow for the formation of very large and complex molecules, with a very high number of configurations. Food sources have to be comprised of molecules that can be used by living organisms, and carbon based organic molecules can.
What features of the element carbon allow it to form the backbone of such a varied array of different compounds?
Carbon has a unique ability to form strong covalent bonds with other carbon atoms and a variety of other elements. Its tetravalency allows it to form stable structures through single, double, and triple bonds. This versatility enables carbon to form long chains, branched structures, and ringed compounds, leading to a wide range of organic molecules with diverse properties and functions.
Why are carbon-based molecules so common in living things?
Carbon atoms have unique bonding properties that allow them to form stable and diverse molecular structures, making them ideal for building the complex molecules necessary for life. This versatility allows carbon-based molecules to form the backbone of biomolecules such as proteins, carbohydrates, and lipids. Additionally, carbon can form strong covalent bonds with other elements like hydrogen, oxygen, and nitrogen, creating a vast array of compounds that can support the processes of life.
How do carbon atoms combine when forming molecules such as glucose or fatty acids?
Carbon atoms combine by sharing electrons in covalent bonds. In glucose, carbon atoms form a ring structure with hydrogen and oxygen atoms attached to each carbon. In fatty acids, carbon atoms form a long chain with a carboxyl group at one end and a methyl group at the other end. These combinations allow for the formation of complex organic molecules with specific properties and functions.
Is dissolving carbon dioxide in water a chemical or physical reaction?
Dissolving CO2 in water would be a physical reaction because neither the CO2 molecules, nor the H2O molecules are undergoing any change.
What molecules in your body that allow us to digest complex carbohydrates?
catabolic molecules
Cell membranes usually allow what substances to enter a cell?
Cell membranes usually allow water, gases (such as oxygen and carbon dioxide), and small uncharged molecules to enter a cell. Larger molecules or charged ions may require specific transport proteins or channels to cross the membrane.
What do carbons special bonding ability allow carbon to do?
Carbon's special bonding ability allows it to form a wide variety of molecules with different shapes and sizes, giving rise to the diversity seen in organic compounds. This ability allows carbon to create complex structures, such as long chains, rings, and branches, which are essential for the formation of biological molecules like proteins, carbohydrates, and nucleic acids. Carbon's bonding versatility also enables it to form strong covalent bonds with other elements, contributing to the stability and structural integrity of these molecules.
