Answer:
Explanation:
In cellular biology, active transport is the movement of molecules across a membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.
Explanation:
with in the food chain energy can be passed and transferred from one organism to an other. plant harvest their energy from Sun during photosynthesis this energy can then be passed from one organism to another in the food chain. the organism that opens energy from sunlight is called the producer .
The right answer is False.
An enzyme is a protein with catalytic properties. They catalyze chemical reactions in cells or outside the cells.
An enzyme specifically activate and accelerate the rate of a reaction. The enzyme is not modified during the reaction (it doesn't get used up). The initial molecules are the substrates of the enzyme, and the molecules formed from these substrates are the products of the reaction.
Protozoans, bacteria, fungi... viruses are not organisms
