1. Complete oxidation of glucose to CO2 and H2o generate the most ATP at what level?

a. glycolisis
b. pyruvate oxidation to Acetyl CoA
c. Krebs cycle
d. Oxidative phosphorylation
e. Substrate level phosphorylation

My answer: a produce 2atp, b produce 2, c 24, d 32, e 2
So, it is d. am I right? :shock:

2. Protein is denatured when

a. it became insoluble in water
b. peptide bond is broken
c. its biological activity is denatured

My answer: c :D

3. Which statement is not true about Km?

a. doesn’t change in presence of excess substrate
b. constant
c. not specific
d. decrease in presence of competitive inhibitors
e. low when reaction rate is high

My answer: d :shock:

4. Which is not oxidized through aerobic respiration?

a. sucrose
b. lipid
c. nucleic acid
d. protein
e. glucose

My answer: c because it sound sooooo out of place here 8)

5. Which is not true regarding Golgi body?

a. analogous to dictyosome in plant structure
b. has two faces
c. cisterna or forming faces toward endoplasmic reticulum
d. involve in packaging and secretion of cell products
e. located near cell membrane

My answer: I think b , c, d, and e are true. So, my answer, A :?:

for ur 1st q ans is C not d and for 3 it is b rest is correct as i think
the organisms that survive r not the one which r strongest nor the one which r briliant THEY R THE ONE WHICH RESPOND TO CHANGES IN NATURE FIRST
