Transcribed Image Text:### Bone Matrix
1. **Contains type I collagen as the major protein**
- Type I collagen is the primary protein present in the bone matrix, providing structural integrity and strength.
2. **Resorption can be increased by high levels of PTH secretion**
- Parathyroid hormone (PTH) plays a critical role in regulating bone resorption, with elevated levels enhancing the breakdown of bone tissue.
3. **Contains non-collagenous proteins such as osteocalcin and osteopontin**
- The bone matrix is also composed of non-collagenous proteins like osteocalcin and osteopontin, which are important for bone mineralization and remodeling.
4. **All the above (a, b, and c) are correct**
- All the statements above accurately describe components and processes involved in the composition and function of the bone matrix.
Expert Solution
Step 1
