Like mitochondria, chloroplasts likely originated from an ancient symbiosis, in this case when a nucleated cell engulfed a photosynthetic prokaryote. Indeed, chloroplasts resemble modern cyanobacteria, which remain similar to the cyanobacteria of 3 million years ago.
Your doctor will test your blood glucose in the office. If it is below 100 milligrams of glucose per deciliter of blood (mg/dL), it is normal. Borderline diabetes or prediabetes occurs when your fasting blood glucose is between 100 and 125 mg/dL. A level of 126 mg/dL or above indicates diabetes.
If you have type 2 diabetes, there are two other numbers you need to watch: your blood sugar and your hemoglobin A1c levels. 1  A normal fasting blood sugar is less than 100 mg/dL. 2  Prediabetes is a fasting blood sugar of 100 to 125 mg/dL or an A1c of 5.7%-6.4%.
