Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
Answer:
Explanation:
i don't know but that sucks for you
Answer:
mutualism
Explanation:
It's a symbiotic relationship beneficial to both symbionts.
in this case E. Coli helps with the absorption of Vitamin K and other important vitamins for the human body in the colon. While, Human (host) provides shelter for it
Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
