Active transport requires the cell to form vesicles, while passive transport requires the use of membrane pumps.
B
Active transport requires the cell to expend energy, while passive transport does not.
C
Active transport is the only form of transport that requires the use of protein carriers.
D
Passive transport is the only form of transport that requires the use of protein carriers.

What is occurring in this equation? ATP + H2O --> ADP + Pi + energy
Answers
Answer:
ATP hydrolysis
Explanation:
ATP hydrolysis is the catabolic process whereby an Adenosine triphosphate (ATP) molecule is broken down by the addition of water to form ADP, inorganic phosphate (Pi) and a release of energy. ATP is an high energy storing molecule in living cells. The stored energy is released when it undergoes hydrolysis.
ATP + H2O → ADP + Pi + energy
From the above reaction, energy once stored in ATP is now available for use. This reaction is hence, called HYDROLYSIS because it involves break down of ATP with the aid of water molecule.

Which courses should Don take in high school if he wants to pursue a degree and career in molecular biology? O anatomy and neurobiology O immunology and genetics O history and communications O physics and trigonometry
Answers
Answer:
anatomy and neurobiology
Explanation:
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.
Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.
A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.
