Nissl bodies correspond to which of the following cytoplasmic organelles? A. Golgi apparatus B. Mitochondria C. Nucleoli D. Rough endoplasmic reticulum E. Smooth endoplasmic reticulum

Cells that line the intestines move nutrients from the intestines through the cell and then to the blood stream. These cells have many folds along their plasma membrane called microvilli. What is the function of these folds? O A. increase the volume of the cell O B. increase the surface area of the cell O C. increase protein transport out of the cell D. increase the ATP production within the cell red MacBook Air 吕口 F3 D00 F4 F7 F2 % & 2 3 5 6 %244

curved lines inside the mitochondria are known as what?

What is assumed as the cell membrane function in connection with it as a mechanical structure? Select one: a. Matrix for enzymatic processes b. Control over the membrane potential с. Control over the ionic composition O d. Displacement of organelles

Explain how in oxygenated tissue your cells use your mitochondria to produce energy.

The binding of sodium ions (Na+) to a membrane protein is one of the first steps in initiation of the sodium-potassium pump that moves these ions across the membrane. The picture shows the inital set up in this process. How does the protein get the energy needed to continue the process of moving the (Na+) across the cell membrane? Membrane Protein ONa+ Inside the Cell A. O O Nat oc Outside the Cell Con Mitochondria will attach to the protein and provide the energy to push the Na+ through the protein. Energy from ADP is released and a channel in the membrane protein permanently B. opens, resulting in the passage of the Nat. Energy produced from the difference in solute concentration on both sides of the O c. membrane pulls the Na+ through the protein. Con с ATP attaches to the protein and releases a phosphate, making energy available to OD. change the shape of the protein and allowing the passage of the Nat.

What happens in the cytoplasm? This process is called glycolysis. Two pyruvate (C3H3O3-) molecules are produced in glycolysis. The released energy is used to form a net of two ATP (adenosine triphosphate) molecules. Energy is later released when ATP molecules are broken down. Select what happens: Glucose gets broken down into 2 pyruvate molecules in the cytoplasm outside of the mitochondria. CO2 is absorbed into the mitochondria. Glucose gets broken down into two pyruvate molecules in the mitochondria. X. O A small amount of energy is produced. Observe: Click Next. What happens now? * Two pyruvate move into the mitochondria. Two pyruváte move into the chloroplast. Cop

the structure of the plasma membrane is best described as: two layers of phospholipids stacked on top of each other, with proteins embedded in the phospholipids Oa single layer of proteins and polysachharides mixed together two layers of proteins stacked on top of each other O many sheets of peptidoglycan stacked on top of each other O one layer of triglycerides on top of a layer of proteins
