Options
A. Yes, because all enzymes and electron carriers are functional
B. No, because with a leaky membrane, the proton gradient cannot be maintained
C. No, because leaky membranes inhibit glycolysis
D. No, because leaky membranes do not allow NADH and FADH2 to donate their electrons to the electron transport chain
Answer:
B. No, because with a leaky membrane, the proton gradient cannot be maintained
Explanation:
The proton motive force (PMF) provides the needed pump to generate electrochemical gradients of proton needed for continue influx into the matix of the mitochondria. The proton Influx generates the energy needed by protein ATPase Synthase for synthesis of ATPs by adding inorganic phosphate to ADP to give ATP.
ADP + Pi -----------→ ATP.
If the mitochondria;l intramembrane leaks, then the PMF can not be sustained, therefore electtrochermical gradient which supplies the energy for ATP synthase for ATP synthesis will not be available. Therefore ATP synthesis stops.
Answer:
Gap junctions within the intercalated disks
Explanation: Gap junctions within the intercalated disks allow impulses to be propagated from one cardiac muscle cell to another. It allows sodium, potassium, and calcium ions to flow between adjacent cells, propagating the action potential, and ensuring coordinated contractions.
D.8
Outermost shell means valence electrons and the 36th element (krypton) has 8 valence electrons
Answer: The brain is the vital organ in humans and each part of brain exhibit a distinct function.
Explanation:
The frontal part of the brain is responsible for controlling the cognitive skills, movement of the body, emotions, memory, judgement, sexual activity, linguistic skills, and others. It controls the behavior. It is the overall control panel of the human body. If the frontal lobe is damaged then this can negatively affect the human personality. The person suffers from difficulty in concentrating as well as planning.
Scientists are still doing research and we just need to be patient. :) :)
