<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.

Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction

Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Which structures are found on sponges?
PSYCHO15rus [73]

Answer:

The special cells of the sponge include those that filter sea water; cells that are phagocytic (that engulf and digest food particles); those that form the external 'skin', breathing pores and tubes through which water enters and leaves the body; and those that secrete the mineral and organic skeletons, called spicules and fibres, respectively. Sponges are also unique because nearly all their cells can change function as required (totipotency).

16. Consider the overall chemical reaction for cellular respiration.
RoseWind [281]

Answer:

Reactants of the cellular respiration process are:

1. C6H12O6

The phase reactant  is used: Glycolysis

Location: cell cytoplasm

In cellular respiration, the glucose is used up in the phase known as glycolysis which is performed in the cell cytoplasm that breaks the glucose into 2 molecules of pyruvate.

2. 6O2

The phase reactant  is used: oxidative phosphorylation

Location: mitochondrial matrix

Oxidative phosphorylation is the phase of cellular respiration that forms the ATP by the transfer of the electron to the oxygen which reduced the oxygen to water.

Products of cellular respiration are -

1. 6CO2

The phase reactant  is used: Krebs cycle

Location: mitochondrial matrix

2. 6H2O

The phase reactant  is used: oxidative phosphorylation

Location: mitochondrial matrix inner membrane

3. 38ATP

The phase reactant  is used: oxidative phosphorylation, Glycolysis, Krebs cycle

Location: mitochondrial matrix, cell cytoplasm and inner membrane mitochondrial matrix
