Answer:
g = 66.7 ms^-2 (3 s.f.)
Explanation:
Potential Energy -> PE
m -> mass
g -> acceleration due to gravity
h -> height
using the formula, PE = mgh
600 = 3 × g × 3
9g = 600
g = 600/9
g = 66.666
g = 66.7 ms^-2 (3 significant figures)
Answer:
Option-C
Explanation:
The mitochondria organelle is a membrane-enclosed organelle which perform the function of producing energy in the cells.
The inner membrane layer of the mitochondria is adapted in a way that increases the surface for the enzyme which produces an energy molecule called ATP. Therefore the enzymes that synthesize the ATP molecule are known as the ATP molecule.
The ATP in the cell is produced by a complex process known as cellular respiration. The citric cycle takes place in the matrix of the mitochondria.
Thus, Option-C is the correct answer.
Answer:
Explanation Aerobic respiration needs oxygen. It is the release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of oxygen:
glucose + oxygen → carbon dioxide + water
C 6H12O6 + 6O 2 → 6CO 2 + 6H2O
