Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.
Explain the role of carbon in biological systems and why it is considered the backbone of life.
Describe the significance of hydrogen in biological systems, particularly in relation to water and energy transfer.
Discuss the role of oxygen in cellular respiration and its importance for energy production in cells.
Explain the importance of nitrogen in biological systems, particularly in the context of amino acids and nucleic acids.
Describe the role of sulfur in biological systems, particularly in the context of protein structure and function.
Explain the role of iron in the human body and describe what happens when there is an iron deficiency.
Discuss the importance of iodine in the human body and the consequences of iodine deficiency.
Describe the role of magnesium in cellular processes and what might occur if magnesium levels are too low.
Explain how trace elements like iron, iodine, and magnesium are obtained from the diet and why a balanced diet is important for maintaining adequate levels of these elements.
Discuss the role of trace elements in enzymatic functions and provide examples of enzymes that require iron, iodine, or magnesium as cofactors.
Explain how the valence electrons of carbon contribute to its ability to form diverse biological molecules.
Describe how the valence electrons of oxygen contribute to its role in water molecules and hydrogen bonding.
How do the valence electrons of nitrogen contribute to its role in amino acids and proteins?
Explain how the valence electrons of phosphorus contribute to its role in nucleic acids like DNA and RNA.
Discuss how the valence electrons of sulfur contribute to its role in proteins, particularly in the formation of disulfide bonds.
Explain the role of carbon in biological systems and why it is considered the backbone of life.
(Student response here)
Carbon is fundamental to biological systems because it forms the backbone of organic molecules, including carbohydrates, proteins, lipids, and nucleic acids. Its ability to form four covalent bonds allows for the creation of complex and diverse molecules necessary for life. Carbon's versatility enables the formation of long chains and rings, which are essential for the structure and function of cells and organisms.
Which property of carbon makes it essential for forming the backbone of organic molecules in biological systems?
