A Cell Is Placed in a Solution of Large Nutrient

question 71

Multiple Choice

A cell is placed in a solution of large nutrient molecules tagged with a red dye.Soon the cell is dark red,showing a concentration of the nutrient much higher than the external solution.We add a reagent that blocks the use of ATP.What result would you expect from this experiment?

• A) The nutrient would continue to rapidly enter the cell by diffusion because as a nutrient it is constantly being used in cell metabolism, so the cell will get redder.
• B) The color will remain the same since all future transfer will stop.
• C) The color will fade as the import of the nutrient stops and diffusion evens the concentrations.
• D) The cell will continue to get darker since the import of the nutrient does not involve ATP.
• E) The cell will die without access to ATP.

Bipolar Cells

Types of neurons in the retina of the eye that play a crucial role in visual processing by transmitting information from photoreceptors to ganglion cells.

Rods and Cones

Photoreceptor cells in the retina of the eye responsible for vision; rods detect light intensity and are crucial for night vision, while cones are responsible for color vision and visual acuity.

Feature Detectors

Neurons in the brain that identify specific features of a stimulus, such as edges, lines, or movements, enabling the recognition of patterns and objects.

Visual Processing

The interpretation of visual information by the brain from input received through the eyes, involved in recognizing, analyzing, and making sense of visual stimuli.
