Answer:

Explanation:

AP Biology Question:

Scientists are testing substance  L  to determine how it enters mammalian cells in a culture. The cells maintain a   120 millimolar (mM)  intracellular concentration of substance  L . The scientists determined the rate of entry of substance  L  into the cells at various external concentrations of substance  L (10 to 100 mM)  in culture medium (Table 1).

Would a muscle cell be able to produce a functional contraction if it lacked t-tubules?
hjlf

The answer would be no. T-Tubules or Transverse tubules are additions of the sarcolemma that infiltrate into the center of cardiac and skeletal muscle cells. There would be no functional contraction since it would not be capable to communicate or interconnect with the other cells.

Which of the following would interfere most with the ability of an enzyme to catalyze a reaction? Reduced concentration of subst
Sidana [21]

<u>ANSWER:</u>

"Reduced concentration of substrate" available can interfere with the "ability of an enzyme" to catalyse a reaction. The main use of enzymes is to increase "the rate of reactions".

<u>EXPLANATION:</u>

  • There are several factors that have an impact on the ability of an enzyme to catalyse a reaction.
  • These include temperature, pH levels, and the quantity of substrate as well as the reactant. When the "substrate concentration increases", the rate of the reaction also increases in the presence of an enzyme.
  • On the other hand, when the "substrate concentration is low", the enzyme cannot catalyse the reaction at a fast rate.
