Answer:
Enzyme Activity- Responsible reactions Enzyme catalyze nearby substrates
Cell to Cell Recognition- Recognize molecules on surface of the other cells
Cell Signalling- A chemical messenger that binds a membrane protein causing to change shape and relay the message inside a cell.
Transport materials- Provides channels for a certain solutes to pass through membrane
Answer:
The correct answer is option c. "Enzyme lowers the activation energy".
Explanation:
The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
Answer:
This electron handoff from NADH to FMN, as opposed to direct reduction of CoQ by NADH, a critical component of the electron transport chain is important for Signaling Transduction and Metabolomics
Explanation:
The NADH-CoQ reductase reaction is catalyzed by Complex I. In this course of activity, following events takes place-
a) FNM (NADH dehydrogenase flavoprotein) is reduced by the NADH to FMNH2 through following reactions –
NADH+H++E-FMN↔NAD++E-FMNH2
b) In the next phase coenzyme Q receives electron from FMNH2 through the the iron–sulfur centers of the NADH-CoQ reductase
c) The iron atom undergoes oxidation–reduction cycles to conserve mitochondrial protein as lataxin and hence transport protons from the matrix to the intermembranal space thereby Signaling Transduction and Metabolomics
Answer:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
