Where does glycolysis take place within the cell quizlet?
In what cells does glycolysis occur?
Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
What happens when glycolysis is inhibited?
Hexokinase, the enzyme catalyzing the first step of glycolysis, is inhibited by its product, glucose 6-phosphate. In turn, the level of glucose 6-phosphate rises because it is in equilibrium with fructose 6-phosphate. Hence, the inhibition of phosphofructokinase leads to the inhibition of hexokinase.
How glucose and protein are each processed in the normal kidney?
Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule. This reabsorption is effected by two sodium-dependent glucose cotransporter (SGLT) proteins.
Why is it important to reabsorb glucose?
In order to ensure that valuable molecules like glucose and amino acids aren’t excreted together with the waste products, the kidney must reabsorb them. Glucose reabsorption is a process that takes place in the proximal tubule.
Can kidney problems cause low blood sugar?
Kidney disease and the risk for low blood sugar Whether or not someone has diabetes, a person with CKD is at risk for low blood sugar because of changes in appetite and meal routine. When kidney function declines insulin and other diabetes medications remain in the system longer because of decreased kidney clearance.
What diseases cause low blood sugar?
Disorders that lower hormone production by the pituitary and adrenal glands (most notably Addison disease) can cause hypoglycemia. Other diseases, such as chronic kidney disease, heart failure, cancer, and sepsis, may also cause hypoglycemia, especially in critically ill people.
Can you have low blood sugar and not be diabetic?
Non-diabetic hypoglycemia, a rare condition, is low blood glucose in people who do not have diabetes. Clinicians usually want to confirm non-diabetic hypoglycemia by verifying classic symptoms along with a low sugar level AND these symptoms recover after eating sugar
What could we teach the patient about how do you identify hypoglycemia?
Initial signs and symptoms of diabetic hypoglycemia include:
- Fast heartbeat.
- Inability to concentrate.
- Irritability or moodiness.
What happens to your body when your blood sugar drops?
Low blood sugar levels can also cause a variety of problems within your central nervous system. Early symptoms include weakness, lightheadedness, and dizziness. Headaches can occur from a lack of glucose, especially if you have diabetes. You may also feel signs of stress, such as nervousness, anxiety, and irritability.
What are symptoms of high blood sugar?
If your blood sugar level is too high, you may experience:
- Increased thirst.
- Frequent urination.
- Nausea and vomiting.
- Shortness of breath.
- Stomach pain.
- Fruity breath odor.
- A very dry mouth.
