Answer: A(secondary active transport)
Explanation:
Secondary active transport, is transport of molecules across the cell membrane which utilizes energy created by co-transporter pumping of ions across the membrane in an electrochemical gradient.
The reabsorption of glucose from the proximal tubule occurs via secondary active transport.
The reabsorbption of glucose does not depend the concentration gradient but on the reabsorption of sodium a co-transporter.
ATP is used in the movements of Na+/K+. Energy is also produced from sodium electrochemical gradient concentration and it is enough energy to transport glucose across the membrane into the epithelial cells.
It would be C chemical change
The sandwich has 367 calories.
Explanation:
- Carbohydrates and proteins provide 4 calories each per gram while fat provides 9 calories per gram. To calculate the total calories, multiply the respective grams with their calorie count.
⇒ 42 × 4 + 7 × 9 + 34 × 4 = 168 + 63 + 136 = 367 calories
Viruses are not made of cells. All living things are made of cells.
I remember the mitochondria breaking down sugars to create energy.
