Bio Ch 5 Quiz
In the following figure, which cell exhibits the condition of plant cells that have been placed in a hypertonic environment? - Both a & b - b - a - c - Both b & c
c
Identify which of the following statements is not true. - When ATP becomes ADP + P, the amount of energy released is enough for a biological purpose. - ATP is formed when energy is released during cell respiration. - ATP is comprised of a sugar, base, and two phosphate groups. - ATP contains the energy form used for cellular work. - ADP is low in potential energy.
ATP is comprised of a sugar, base, and two phosphate groups.
Enzymes are named based on the substrate that they bind. This is possible because - enzymes all have the same shape. - enzymes are used up in the reaction. - an enzyme binds one specific substrate. - enzymes speed up the rate of a reaction. - an enzyme is only associated with one metabolic pathway.
an enzyme binds one specific substrate.
The figure below demonstrates which key concept regarding cell activities? - enzyme inhibition - the first law of thermodynamics - coupled reactions - active transport - receptor-mediated endocytosis
coupled reactions
What process typically regulates the enzymes involved in metabolic reactions? - feedback inhibition - ATP blockage - temperature levels - entropy capture - substrate inhibition
feedback inhibition
The figure below reflects how these two cells would respond in a(n) ________ environment. - hypertonic - ionic - diffuse - hypotonic - isotonic
hypertonic
Which of the types of cellular activities listed below would not use ATP? - protein synthesis - flagella movement - passive transport - active transport - muscular contraction
passive transport
A white blood cell surrounds and engulfs a worn-out red blood cell, forming a vesicle around the red blood cell. This process is called - phagocytosis. - exocytosis. - pinocytosis. - active transport. - facilitated diffusion.
phagocytosis.
What prevents a plant cell from bursting in a hypotonic solution? - water moving out of the cell - the presence of chloroplasts - transport proteins, which help pump the excess water out of the cell - the presence of a cell wall - plasma membrane
the presence of a cell wall
In feedback inhibition of a metabolic pathway, where does the inhibitor bind? - to a substrate or the product of the last reaction - to the enzyme of the first reaction - to the enzyme of the last reaction - to the substrate of the first reaction - to the product of the first reaction
to the enzyme of the first reaction
