Following are important questions and answers for IPE Exams in AP and
Telangana for Senior Intermediate. These are 2 marks questions from
the chapter - Respiration in Plants.
Q: What is the specific role of F0 - F1 particles in respiration?
A: F0 - F1 particles (Previously called Oxysomes or elementary
particles) are present in the inner membrane of mitochondria (or
thylakoid membranes of chloroplast). They are considered as Complex V
(ATP synthase). F0 is hydrophilic and present towards
perimitochondrial space. F1 is hydrophobic and present towards matrix.
F0 acts H+ channel. F1 is the smallest rotating machine and active
site of ATP synthesis.
Q: When does anaerobic respiration occur in man and yeast?
A: Anaerobic respiration occurs in muscle cells of man, and yeast when
oxygen is not available.
Q: What cellular organic substances are never used as respiratory substrates?
A: Pure proteins and fats are never used as respiratory substrates.
Q: Why is the RQ of fats less than that of carbohydrates?
A: When fats are used as substrates in respiration, less CO2 is
evolved for more O2 absorbed. So RQ is less than that of carbohydrates
(i.e. less than 1).
Q: What is meant by 'Amphibolic' pathway?
A: The respiratory pathway is an amphibolic pathway as it involves
both anabolism and catabolism. Basically it is catabolic pathway. But
the carbon skeleton produced during respiration is used as a precursor
for biosynthesis of other biomolecules.
Ex: á - Ketoglutaric acid is useful in the synthesis of an amino acid
called Glutamic acid.
Q: Name the mobile electron carriers of the respiratory electron
transport chain in the inner mitochondrial membrane.
A: Ubiquinone (UQ) is a mobile electron carrier between Complex I &
Complex III, Complex II and Complex III. Cyt C is a mobile electron
carrier between Complex III and Complex IV of the mitochondrial inner
membrane.
Q: What is the final acceptor of electrons in aerobic respiration?
From which complex does it receive electrons?
A: Oxygen is the final acceptor of electrons in aerobic respiration.
It receives electrons from Complex IV.
Q: Do you know of any step in Krebs Cycle where there is a substrate
level phosphorylation? Explain.
A: During the conversion of succinyl - CoA to succinic acid a molecule
of GTP is synthesised. This is a substrate level phosphorylation
(SLP). In a coupled reaction GTP is converted to GDP with simultaneous
synthesis of ATP from ADP.

AP EAMCET 2016 on 29th April - Telangana EAMCET on 2nd May 2016
The Government of Andhra Pradesh has changed the AP EAMCET 2016 date. The exam will now be conducted on 29th April 2016 instead of earlier date of 5th May 2016.
The date has been changed due to KCET 2016 (Karnataka Common Entrance Test) on 5th May 2016. Many candidates from Andhra Pradesh also appear for KCET along with EAMCET and TANCET.
The JNTU Kakinada will conduct the AP EAMCET 2016 examination. The TS EAMCET 2016 will be held on 2nd May 2016 across the state of Telangana. Several students from AP also appear for Telangana EAMCET.
Candidates who wish to join in engineering colleges in Hyderabad and Telangana have to appear and qualify in Telangana EAMCET 2016. More details will be announced along with notification.
