Which cells secrete collagen and stimulate calcium phosphate deposition?
Osteoblasts are responsible for secreting collagen and stimulating calcium phosphate deposition during the process of bone formation.
Will calcium phosphate precipitate?
Calcium phosphate can precipitate under certain conditions, typically when the concentrations of calcium ions and phosphate ions in a solution exceed their solubility product (Ksp). This often occurs in biological systems, such as in the formation of bone and teeth, or in industrial processes. Factors such as pH, temperature, and the presence of other ions can influence the precipitation process. If conditions favor supersaturation, calcium phosphate will crystallize out of the solution.
How does calcium form in the bladder?
Calcium forms in the bladder primarily through the precipitation of calcium salts when urine becomes supersaturated with calcium and oxalate or phosphate. Factors contributing to this include dehydration, high dietary calcium intake, or metabolic disorders. When these conditions exist, minerals can crystallize and aggregate, leading to the formation of bladder stones or calcifications. This process can be influenced by urine pH and other urinary constituents.
What is the depostion of minerals within the cartilage?
Minerals such as calcium and phosphorus can deposit within cartilage, leading to a condition known as calcification. This process may result in the hardening of cartilage and can impair its flexibility and function. Cartilage calcification can be associated with aging, injury, or certain medical conditions.
What is a true statement regarding calcium in the bone matrix?
A true statement regarding calcium in the bone matrix is that it exists primarily in the form of hydroxyapatite crystals, which provide structural rigidity and strength to bones. These crystals consist of calcium phosphate and are integral to bone mineralization, facilitating the storage of calcium and phosphate ions. This mineralization process is crucial for maintaining bone density and overall skeletal health.
Calcium phosphate stored in soil and rock dissolves in water as part of the?
Calcium phosphate stored in soil and rock dissolves in water as part of the natural weathering process. This dissolution releases calcium and phosphate ions into the water, which can then be taken up by plants for growth and development. Over time, this process contributes to the cycling of calcium and phosphorus in ecosystems.
Which cells secrete collagen and stimulate calcium phosphate deposition?
Osteoblasts are responsible for secreting collagen and stimulating calcium phosphate deposition during the process of bone formation.
What is the typical process for exploiting an ore deposit?
The deposit is located, a grade is assessed, minerals are extracted, and the site is reclaimed

How can one make phosphorus?
Phosphorus can be made through a process called the thermal decomposition of calcium phosphate. This involves heating calcium phosphate with silica and carbon in a furnace to produce phosphorus vapor, which can then be condensed into a solid form.

Reaction of phosphate with calcium hydroxide?
Phosphate will form insoluble calcium phosphate (Ca3(PO4)2) when it reacts with calcium hydroxide (Ca(OH)2). This process is commonly used in water treatment for removing phosphates from wastewater by forming a precipitate that can be easily removed.
What is correct definition of ossification?
replacement of cartilage with osteocytes
What is bone synthesis?
Precipitation of the salt calcium phosphate among fibers of the protein type I collagen. This results from raising the concentrations of calcium ions and phosphate ions beyond their "solubility product" concentration. This occurs next to special cells called osteocytes, and not inside their cytoplasm. Nobody has discovered the mechanism by which osteocytes pump high concentrations of calcium ions and also high concentrations of phosphate ions into the same locations. One theory is that a special protein ("osteoid") binds to both calcium ions and phosphate ions, so that they precipitate at concentrations that would not be high enough to cause precipitation if no osteoid were present. If you know how osteocytes cause bone synthesis, then you should publish this information in a refereed journal, such as Nature. akharris@bio.unc.edu
A mineralized shell?
No
How can weathering contribute to the formation of a mineral deposit?
Weathering can contribute to the formation of a mineral deposit by breaking down rocks and exposing minerals within them. This process can release minerals into the environment, where they can accumulate and form deposits over time.
