Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
Each Hb protein can carry up to four oxygen molecules.

Verified step by step guidance

1. Step 1: Understand the structure of hemoglobin (Hb). Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen. It consists of four subunits, each containing a heme group capable of binding one oxygen molecule.
2. Step 2: Analyze the statement provided. The statement claims that each Hb protein can carry up to four oxygen molecules. Based on the structure of hemoglobin, this is correct because each of the four heme groups can bind one oxygen molecule.
3. Step 3: Confirm the accuracy of the statement. Since hemoglobin has four heme groups and each can bind one oxygen molecule, the statement 'Each Hb protein can carry up to four oxygen molecules' is true.
4. Step 4: If the statement were false, you would need to correct it. For example, if the statement incorrectly claimed that Hb can carry more or fewer than four oxygen molecules, you would revise it to reflect the correct number based on hemoglobin's structure.
5. Step 5: Conclude that the statement is true and does not require correction. Hemoglobin's ability to carry up to four oxygen molecules is a fundamental concept in understanding oxygen transport in the blood.

Key Concepts

Hemoglobin Structure

Hemoglobin (Hb) is a protein found in red blood cells responsible for transporting oxygen. It consists of four subunits, each containing a heme group that can bind one oxygen molecule. This quaternary structure allows hemoglobin to effectively pick up oxygen in the lungs and release it in tissues.

Oxygen Binding Capacity

The oxygen binding capacity of hemoglobin refers to its ability to carry oxygen molecules. Each hemoglobin molecule can bind up to four oxygen molecules due to its four heme groups. This property is crucial for efficient oxygen transport throughout the body, ensuring that tissues receive adequate oxygen for metabolism.

True/False Statements in Science

In scientific contexts, true/false statements are used to assess understanding of factual information. A true statement accurately reflects established scientific knowledge, while a false statement requires correction to align with scientific facts. This exercise helps reinforce learning and comprehension of key concepts.
