1.1 Inorganic Ions Flashcards
(19 cards)
What are inorganic ions also called?
Inorganic ions are also called electrolytes or minerals. They are important in many cellular processes.
What does inorganic mean in terms of molecules or ions?
Inorganic refers to a molecule or ion that has no more than one carbon atom.
What does organic mean in terms of molecules?
Organic refers to molecules that have a large proportion of carbon atoms.
What are micronutrients?
Micronutrients are nutrients that are needed in very small concentrations.
What are macronutrients?
Macronutrients are nutrients that are needed in small concentrations.
What is the importance of Magnesium (Mg2+) in plants?
Magnesium is needed for photosynthesis in plants. A deficiency of magnesium causes chlorosis, which is a yellowing of the leaves.
What is the importance of Magnesium (Mg2+) in animals?
Magnesium is needed for the development of bones in animals.
What is the importance of Iron (Fe2+) in plants?
Iron is needed as a cofactor in chlorophyll synthesis in plants.
What is the importance of Iron (Fe2+) in animals?
Iron is a component of hemoglobin in animals, which is responsible for the transport of oxygen in the blood. A deficiency of iron can lead to anemia.
What is the importance of phosphate ions (PO43-) in both plants and animals?
Phosphate ions are a component of DNA, RNA, and ATP. They are also a component of phospholipids found in the plasma membranes of both plants and animals.
What is the importance of Calcium (Ca2+) in plants?
Calcium is a component of the middle lamella of cell walls in plants, providing structure and support.
What is the importance of Calcium (Ca2+) in animals?
Calcium is a component of bones and teeth in animals, contributing to their strength and structure.
What are metabolic reactions?
Metabolic reactions are chemical reactions that take place inside living cells or organisms to maintain life.
What are anabolic reactions?
Anabolic reactions are metabolic reactions that involve the building up of molecules.
What are catabolic reactions?
Catabolic reactions are metabolic reactions that involve the breaking down of molecules.
What is an organic compound?
An organic compound is a compound that contains carbon and hydrogen and is produced by a living organism.
What is an inorganic compound?
An inorganic compound is a compound that does not contain carbon and hydrogen and is not produced by living organisms.
What is a macronutrient?
A macronutrient is a nutrient that is required by a living organism in small quantities, such as iron and calcium.
What is a micronutrient?
A micronutrient is a nutrient that is required by a living organism in very small quantities, such as copper and zinc.
