With reference to photosynthesis, what is the $CF _0$ - $CF _1$ complex?

ATP is known as energy currency of a cell. ATP is synthesized from ADP and Pi. The reaction is catalyzed by an enzyme called as ATP synthase. When the enzyme and substrate (ADP) are distant inside the cell, the reaction cannot take place spontaneously. Which of the following statements best explains the cause for the ATP synthase and ADP to interact?

How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to $CO _2$ and $H _2O$ yields $686$kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is $12$kcal?

Calvin cycle has three stages.
$1$. Reduction during which carbohydrate is formed at the expense of photochemically made ATP and NaDPH.
$2$. Regeneration during which carbon dioxide acceptor $1, 5$-RuBP is formed.
$3$. Carboxylation during which $CO _2$ combines with $1, 5-$RuBP.
Identify the correct sequence.

A universal hydrogen acceptor in an electron transport system is ___________.

The idea that pH gradients could provide energy for ATP formation in chloroplasts and mitochondria was first proposed by ____________.

Which of the following step of photosynthesis is not directey involve in ATP synthesis or consumption?

Direct gain of ATP from one mole of glucose during glycolysis or EMP pathaway ____________.

Photosynthetic oxygen producing cells differ from non-oxygen producing cells in that the former.

Mitochondrial morphology is maintained by balancing the active absorption of water and active secretion by the mitochondrion. Hence mitochondria are likely to swell in the presence of.
