Answer:
The correct answer is TRUE
Explanation:
A process that requires cellular energy to move a substance against its concentration gradient is called.
Active transport moves molecules from one side of the membrane to the other against their electrochemical gradient. It needs energy to occur. The answer is active transport.
What is active transport?Active transport is one of the three cellular transmembrane transports. The other two are passive transport and simple diffussion.
Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side of the membrane to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.
Carrier proteins are involved in active transport.
Hence, the process that requires cellular energy to move a substance against its concentration gradient is called Active transport.

Use the mitosis and meiosis interactive to help you identify the images as a cell in metaphase of mitosis, meiosis I, or meiosis II. All cells come from an organism that has a diploid (2n) chromosome number of eight.
In this case, the images are not found here but a cell in meiosis has undergone a reduction in the genetic material.
What is meiosis?Meiosis is a reductional type of cell division where chromosome number is reduced to half (haploid number n: 4).
In this case, meiosis will produce four cells having 4 chromosomes each (2n: 8 chromosomes in mitosis).
In conclusion, the images are not found here but a cell in meiosis has undergone a reduction in the genetic material.

The following statements about the light reactions of photosynthesis are all true except: Question 3 options: Chlorophyll (and other pigments) absorb light energy, which excites electrons. Electrons are transferred from water to NADP . RUBP carboxylase catalyses absorbtion of photons. ATP is generated by photophosphorylation. The splitting of water molecules provides a source of electrons.
The wrong statement is : ( C ) RUBP carboxylase catalyses absorption of photons
Light reaction of photosynthesisThe light reaction of photosynthesis is a stage in photosynthesis which is light dependent.
During the light reactions of photosynthesis, the green plant chlorophyll absorbs light energy, and the absorbed energy makes the electrons to get excited ,also electorns are transferred from water to NADP⁺ also ATP is generated by photophosphorylation.
But the RUBP carboxylase catalyses absorption of photons does not occur in the light reaction of photosynthesis.
Hence we can conclude that the wrong statement is : ( C ) RUBP carboxylase catalyses absorption of photons
