Lactose intolerance is caused by:

A. inadequate exposure to dairy products
B. too much lactase in the diet
C. the lack of or reduction of the enzyme lactase
D. lack of hydrochloric acid in the gut lack of amylase

Aprocess in green plants that involves the use of carbon dioxide and water in the production of glucose and oxygen using the suns energy

What is the next step in the process after a substrate enters the active site of an enzyme

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
