Explanation

• 2 ATP molecules are consumed in the initial steps
• 4 ATP molecules are produced in the later steps

Explanation

Explanation

In human genetics, the sex chromosomes are X and Y.

Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).

When a father passes on his chromosomes to his offspring, he can only contribute either an X or a Y chromosome.

If he passes on his Y chromosome, the child will be a boy (XY).

If he passes on his X chromosome, the child will be a girl (XX).

Therefore, the father can only transfer his Y chromosome to his son.

Explanation

The function of the Golgi complex is processing of cell secretions.

It modifies, sorts, and packages proteins and lipids produced in the endoplasmic reticulum for secretion or for use within the cell.

Explanation

Chloroplasts are membrane-bound bodies containing pigment.

Specifically, they contain chlorophyll, which is essential for photosynthesis.

It allowing plants to convert light energy into chemical energy.

Explanation

The hydrophilic end of a phospholipid molecule is polar because of the presence of a phosphate group.

The phosphate group contributes to the molecule's polarity.

It allowing it to interact with water, in contrast to the hydrophobic fatty acid tails.

Explanation

In the journey of electrons from photosystem II to photosystem I, plastocyanin is reduced by the cytochrome complex.

The cytochrome complex facilitates the transfer of electrons to plastocyanin, which then carries them to Photosystem I.

Explanation

In the Calvin cycle, CO₂ reacts with RuBP to produce a 6-carbon unstable intermediate.

This intermediate quickly splits into two molecules of 3-PGA (3-phosphoglycerate) as part of the carbon fixation process.
