Working and editing Woocommerce Hooks to change functionalities - php

Question

I'm working with WooCommerce and I'm changing some functionalities in my home page.
My theme uses "Woocommerce Hooks" but I only see where calls the function. What I need is to find that function and change it.
In my case I saw that the code I want to change is in "/plugin/component/wc_product.php" and there I see this piece of code:
<ul class="products">
<?php while ( $products->have_posts() ) : $products->the_post(); ?>
<?php if( "default" == $tpvc_wc_product_style ) : ?>
<?php wc_get_template_part( 'content-product' ); ?>
<?php else : ?>
<?php wc_get_template_part( 'content-product', 'alt' ); ?>
<?php endif; ?>
<?php endwhile; // end of the loop. ?>
</ul>
But when I go to "/theme/woocommerce/content-product.php" I only see this code:
<li <?php post_class(); ?>>
<div class="product-inner">
<?php
/**
* woocommerce_before_shop_loop_item hook.
*
* #hooked woocommerce_template_loop_product_link_open - 10
*/
do_action( 'woocommerce_before_shop_loop_item' );
/**
* woocommerce_before_shop_loop_item_title hook.
*
* #hooked woocommerce_show_product_loop_sale_flash - 10
* #hooked woocommerce_template_loop_product_thumbnail - 10
*/
do_action( 'woocommerce_before_shop_loop_item_title' );
/**
* woocommerce_shop_loop_item_title hook.
*
* #hooked woocommerce_template_loop_product_title - 10
*/
do_action( 'woocommerce_shop_loop_item_title' );
/**
* woocommerce_after_shop_loop_item_title hook.
*
* #hooked woocommerce_template_loop_rating - 5
* #hooked woocommerce_template_loop_price - 10
*/
do_action( 'woocommerce_after_shop_loop_item_title' );
/**
* woocommerce_after_shop_loop_item hook.
*
* #hooked woocommerce_template_loop_product_link_close - 5
* #hooked woocommerce_template_loop_add_to_cart - 10
*/
do_action( 'woocommerce_after_shop_loop_item' );
?>
</div>
</li>
Where are Woocommerce Hooks functions deployed? Where are that do_action() functions so I can edit them?
Thanks for your help!
