Answer:
The difference between light dependent and light independent reactions is light independent is energy from sunlight that is absorbed by Chlorophyll. Also light dependent is energy that is converted into stored chemical energy. In the independent reactions, the chemical energy basically harvests during the light dependent reactions, which drives the assembly of these sugar molecules from carbon dioxide.
Answer The definitions are matched according to the terminology given below.
Ribosome This organelle is the site of polypeptide assembly. This two part organelle is found in endoplasmic reticulum.
Lysosome The cellular digestion and disposal of biological molecules occur inside this organelle. Mitochondrion Aerobic respiration occur in this organelle.
Endoplasmic reticulum This generally play role in cell defence.
Answer:
repolarization
Explanation:
Potassium channel blockers are drugs that interfere with the flow of potassium ions (K+) through potassium channels in cell membranes, thereby prolonging the duration of the action potential (repolarization phase). For example, amiodarone is a class III antiarrhythmic agent whose target is HERG human cardiac K+ channel. This drug (amiodarone) acts by prolonging the repolarization phase of the cardiac action potential.
Answer:
The partial pressure of oxygen determines the affinity of hemoglobin for oxygen. Red blood cells have the shape of a flattened disk, generating a broad surface area for the diffusion of oxygen. Since their only purpose is carrying oxygen throughout the body, they lack many typical cell structures, including a nucleus.
