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:
<h2>
The organelles are mitochondria and chloroplasts.</h2>
Explanation:
<em>The mitochondria and chloroplasts play a major role in energy conversion that helps to synthezise gene expression products. They were essential to the evolution of present day eukaryotes. These specialized structures are enclosed by double membranes, and they are believed to have originated back when all living thing on Earth were single-celled organisms. The proposed origin of mithocondria and chloroplasts is known as the endosymbiotic hypothesis.</em>
<em>The mithocondria is considered the powerhouses of the cell, it enables eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. Within the eukaryotic cells, mithocondria works like batteries, because they convert energy from one form to another.</em>
<em>The eukaryotic cells may contain several other types of organelles, such as the endoplasmic reticulum, the golgi apparatus and lysosomes. </em>
