Answer: Ras activity would be significantly slower in its response to extracellular signals.
Explanation:
• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)
• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase
• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)
Answer:
bound to oxyheamoglobin
Explanation:.
Oxyheamoglobin is formed from the reaction of oxygen with haemoglobin.it is the oxygen loaded form of haemoglobin for delivery of oxygen to needed remote areas of the body.
.Hb + 4O2 ⇒ HbO8
haemoglobin oxygen oxyhaemoglobin
Haemoglobin is a protein molecule that binds with oxygen. It has high affinity for oxygen with its four haem groups. Each haem group has binding iron.(Fe). When it is binds with oxygen it is bright red, and turns purple when it unloaded oxygen at target point.
It has no association with carbondioixde transports except oxygen transport
.
Carbon dioxide, is transported as the listed three options(b,c,d) in the questions. Therefore bound to oxyheamoglobin is wrong, and it is the correct answer
False, I could be wrong but I’m pretty sure it’s false
The answer should be 4) as it is known that uv radiation might have an effect on dna, thus causing mutations such as skin cancer in humans.
