Question

Which of the following statement is correct about diffusion? A) It is very rapid over long distance B) It is an active process in which molecules move from a region of lower concentration to one of higher concentration. C) It is a passive process in which molecules move from a region of higher concentration to one of lower concentration. D) It requires an expenditure of energy by the cell. E) It requires integral proteins in the cell membrane. In addition to ATP, what are the proudest of glycolysis? A) NADH and pyruvate B) CO_2 and H_2 O C) CO_2 D) H_2 O, FADH_2, and citrate E) CO_2 and NADH Grana, thylakoids, and stroma are all components found in A) lysosomes, B) vacuoles, C) chloroplasts, D) nuclei, E) mitochondria, Which of the following intermediary metabolites enters the citric acid cycle and is formed, in part by the removal of a carbon (CO_2) from one molecule of pyruvate? A) oxaloacetate B) glyceraidehydes-3-phosphate C) lactate D) acetyl CoA E) citrate All of the following part of a prokaryotic cell except A) an endoplasmic reticulum. B) DNA. C) ribosomes. D) a plasma membrane. E) a cell wall. A) Enzyme function is independent of physical and chemical environment factors such as pH and temperature. B) Enzyme increase the rate of chemical reaction by lowering activation energy barriers. C) Enzyme may require a nonprotein cofactor or icon for catalysis to take speed up mode appreciably than if the enzyme act alone. D)Enzyme function is increased if the three-dimensional structure or conformation of any enzyme is altered.

Explanation / Answer

1.c particle move freely in low concentration

2.option A is correct becouse glycolysis involves breaking down of sugarglucose +fructose+sugar to produce energy so end product is 2 pyruvate+NADH

3.option c is correct chloroplast contains chlorophyll stacks of thylakoids is known as grana 4.option D pyruvate release co2 5.A endoplasmic reticulam 6.B increase chemical reaction
